Abstract
The feeding habits and habitats of fish influence the morphology of the oral cavity. This study used gross anatomy, light microscopy, and scanning electron microscopy, in addition to morphometric analysis, to investigate the anatomical characteristics of the oral cavity roof in Pagrus pagrus and Boops boops, which have different dietary habits. The oral cavity roof appeared U-shaped and divided into the palate and upper pharyngeal regions. The upper lip of P. pagrus was broad, while B. boops' upper lip was small and thin. Both species had a stratified squamous epithelium with an irregular shape and a folded surface. P. pagrus had a horseshoe-shaped upper velum with a high middle part, and its surface resembled sea waves with obvious mucous-secreting openings with cilia and many folds and grooves between them. B. boops's upper velum was thin and appeared as a triangle pouch with a pointed cranial apex. The palate in both species was narrow in the front and increased in width backward until it ended. The upper pharyngeal teeth in P. pagrus appeared as two patches, separated by a median longitudinal ridge and an anterior V-shape separator. Meanwhile, in B. boops, they appeared as a ball patch on both sides and a separator ridge in the middle. Because P. pagrus fed on harder structures than B. boops, their feeding habits were reflected in the structure of the oral cavity roof. P. pagrus, a carnivorous species, had several rows of sharp upper jaw and upper pharyngeal teeth, thick spinous tubercles on oblique transverse ridges, and massive mucous glands. On the other hand, B. boops, an omnivorous species, had only one row of upper jaw teeth, a few upper pharyngeal teeth scattered on two oval patches, and thin filaments on the oblique transverse ridges.

Abstract
Near-peer tutoring (NPT) programs are popular vehicles to supplement traditional delivery of medical school curricula, including for anatomy laboratory (AL) content. While NPT programs can result in improved preclinical coursework performance for tutees, little to no data specifically show a benefit of NPT in AL course performance. In 2021, NYIT College of Osteopathic Medicine launched an NPT program where qualified second-year students led group tutoring sessions for first-year students. This study investigated whether participation and level of attendance in AL NPT sessions were associated with greater examination-to-examination improvement in AL performance. Student attendance at AL sessions in the NPT program was categorized as either regular (10 or more sessions), moderate (5-9 sessions), infrequent (1-4 sessions), or never during one semester. For the first 2 years of the NPT program, attendance frequency at AL tutoring sessions had a significant impact on average exam-to-exam improvement (p < 0.05). Overall, students who attended tutoring at any frequency had greater exam-to-exam improvement than students who never attended (p < 0.05). However, this trend was only significant in 1 of 2 years investigated. These data show that NPT programs can, though not uniformly, benefit student outcomes in AL coursework. With these data, this study provides additional details on the level of attendance necessary for expected improvements in AL coursework.

Abstract
The femoral epicondyle is an anatomical bony landmark essential for surgeons and anatomists, but there are discrepancies between the two fields when using this term. In current orthopedic surgery, it commonly denotes the small bony prominence of the femoral condyle. Given the derivation, "epicondyle" should be a region projecting laterally from the articular surface rather than a point. These discrepancies in usage are found not only between the fields but also in the literature. This article reviews the narrative definition of "epicondyle of the femur" in surgery and the evolution of the term in anatomy. The outcomes of the review suggest a relationship between the differing perceptions of the epicondyle and the evolution of the term. In reports of studies related to the epicondyle, it is strongly recommended that the definition of the word is clearly stated, with an understanding of its evolution.

Abstract
Learning human anatomy is essential for Doctor of Physical Therapy (DPT) education. Body donors are traditionally utilized to understand content, but in a hybrid learning environment, students have limited time to use body donors. To improve body donor access and learning, we created online synchronous pre-body donor activities. The impact of these online strategies on students' subsequent exams and final grade were investigated in a non-randomized, observational study. These activities were hypothesized to positively influence students' anatomy performance. In a 16-week semester, DPT students (case [n = 91], control [n = 22]) participated in a hybrid program of asynchronous/synchronous online learning and two in-person immersions. Measures included student course grades and teaching surveys. Spearman's rho correlations analyzed the relationship between four pre-body donor quizzes to body donor exams, written exams, and final course grade. Mann-Whitney U tests assessed differences in grades between cohorts. A linear regression model examined the influence of pre-body donor quizzing on exams/final grades. Correlation tests revealed a strong relationship between the average pre-body donor quiz score and both the first written exam and final course grade (p = 0.0001). The case group achieved significantly higher scores than the control group on the first in-person body donor exam (p = 0.011), the second written exam (p = 0.0001), and the final grade (p = 0.004). The pre-body donor quizzes predicted performance on the subsequent in-person body donor exams, written exams, and the final grade. Implementation of online pre-body donor learning activities was associated with increased academic performance among hybrid DPT students and may aid in learning anatomy concepts for clinical practice.

Abstract
Histological observation under light microscopy has long been used in human cadaveric studies. However, it can distort the interpretations of findings if not used appropriately; there is no guide for its proper use. The aim of this article is to revisit and discuss the correct use of histology in human cadaveric studies, following discussions with experts in multiple fields of medicine, and to create the first guide for such usage. We reached a consensus with the experts, agreeing that when this principle (structure, quantification, interaction, position: SQIP) is applied to histological observations, the findings will be interpreted correctly. Appropriate use of this recommendation can make human cadaveric studies more accurate and informative. This is the first histology guide for human cadaveric studies.

Abstract
Anatomy is an essential component of clinical anesthesiology. The use of simulated patients and alternative materials, including embalmed human bodies, have become increasingly common during resident physician training due to the deemphasis on anatomical education during undergraduate medical training. In this report, the need for a more extensive review of relevant anatomy for the practice of anesthesiology was addressed by the design, evaluation, and dissemination of a human dissection course for procedural training of anesthesiology residents. The course utilized "freedom art" embalmed human bodies that allowed trainees to perform ultrasound-based regional and neuraxial techniques followed by detailed dissections of critical anatomy. One hundred and four residents participated in workshops and small group discussions and were evaluated using pre- and post-course assessments. A variety of clinical techniques were performed on the bodies, including regional blocks and neuraxial catheter placement. Insertion of peripheral/neuraxial catheters was successful, with dissections demonstrating the expected placement. Assessment scores improved following the course (pre-course mean 52.7%, standard deviation (σ) 13.1%; post-course mean 72.2%, σ 11.6%; t-test p < 0.0001) and feedback highlighted the usefulness and clinical relevance of course content. The ability to correlate ultrasound imaging with subsequent dissections of the "blocked" area and visualization of dye staining was extremely relevant for spatial understanding of the anatomy relevant for the clinical practice of these techniques. This manuscript demonstrates successful implementation of a comprehensive course for anesthesiology resident physicians to address gaps in undergraduate anatomical education and suggests that broader adoption of dissection courses may be beneficial for training anesthesiologists.

Abstract
Pelvic anatomy is considered challenging to teach and learn, partly because its complexity can make it difficult to conceptualize. Educational researchers recognize the value of a spiraling curriculum to develop clinically orientated anatomy knowledge for health professionals, but most studies have focused on the preclinical years. It is unclear how the complexities of pelvic anatomy are taught in the clinical setting by clinician educators. Understanding pelvic anatomy teaching from the perspectives of clinician educators is important because of their critical role in supporting medical students to become knowledgeable, safe practitioners. This study sought to examine factors that influence clinician educators' teaching of pelvic anatomy to medical students during clinical placement. Using established qualitative research methods, this exploratory study used semi-structured interviews with 10 participants from obstetrics/gynecology (n = 4) and urology (n = 6) in Australia. Interviews were transcribed, and data were analyzed using a reflexive thematic analysis framework. Two overarching factors were identified as influencing clinician educators' teaching: (1) how they defined the scope of knowledge, and (2) pedagogical understanding. Scope of knowledge was underpinned by patient safety considerations and guided by past experience and student aspirations. Pedagogical understanding also relied on experience and encompassed multiple teaching strategies, including approaches informed by sensitivities surrounding pelvic anatomy. Multiple factors influence how clinician educators define the scope of pelvic anatomy knowledge required of medical students. Clinician educators' awareness of syllabus and teaching approaches can enable them to support students to attain threshold concepts such as three-dimensional spatial relationships and sociocultural sensitivities associated with pelvic anatomy.

Abstract
Physical therapy education has significantly evolved over the past few decades. While gross anatomy is integral to physical therapy education curricula, the current state of anatomy education within these programs is not well understood. The primary purpose of this report was to provide an update on the current state of anatomy education across United States (US) Doctor of Physical Therapy (DPT) programs. A survey was disseminated to all 261 accredited US physical therapy programs. The survey was deployed in November 2020 with a deadline to respond by January 15, 2021. The response rate was 32.6% (85/261). When teaching anatomy, 90.5% of the responding programs used dissection, 71.4% used didactic lectures, 60.7% used computer-assisted technology, 58% used prosections, 23.8% used plastinated models, and 31% reported using other methods. DPT programs have experienced declines in PhD faculty (15.7%) and Master of Physical Therapy faculty (15.3%) and notable increases in DPT (16.5%) and physician faculty (8.2%) teaching anatomy within DPT programs. Despite greater use of computer-assisted technologies, these technologies have not replaced donor-based dissection in DPT programs.

Abstract
Effective communication and precise navigation within the intricacies of the human body rely on robust anatomical terminology. Since its creation by the Federative Committee on Anatomical Terminology (FCAT), the Terminologia Anatomica (TA 1998) has consistently served as the benchmark in the field. However, the constant advancement of anatomical knowledge requires regular revisions, updates, and enhancements of anatomical nomenclature to accommodate the latest scientific discoveries. The recent adoption of the second edition of Terminologia Anatomica (TA 2019) by the International Federation of Associations of Anatomists (IFAA) has drawn attention to certain notable omissions. Despite over a century of dedicated work establishing standard anatomical terminology, specific widely recognized gross anatomical structures are still absent from the official listing in the Terminologia Anatomica. There is, however, a consensus that the inclusion of names for trivial or variably present structures should be avoided. Accordingly, this article focuses on a thoughtfully selected group of anatomical structures, which are so important that they are routinely discussed during anatomy courses, despite their exclusion from the official lists of anatomical terms. These basic structures hold fundamental importance for both anatomy education and clinical practice. Consequently, their appropriate nomenclature warrants consideration for inclusion in future editions of TA.

Abstract
Organismal solutions to natural challenges can spark creative engineering applications. However, most engineers are not experts in organismal biology, creating a potential barrier to maximally effective bioinspired design. In this review, we aim to reduce that barrier with respect to a group of organisms that hold particular promise for a variety of applications: snakes. Representing >10% of tetrapod vertebrates, snakes inhabit nearly every imaginable terrestrial environment, moving with ease under many conditions that would thwart other animals. To do so, they employ over a dozen different types of locomotion (perhaps well over). Lacking limbs, they have evolved axial musculoskeletal features that enable their vast functional diversity, which can vary across species. Different species also have various skin features that provide numerous functional benefits, including frictional anisotropy or isotropy (as their locomotor habits demand), waterproofing, dirt shedding, antimicrobial properties, structural colors, and wear resistance. Snakes clearly have much to offer to the fields of robotics and materials science. We aim for this review to increase knowledge of snake functional diversity by facilitating access to the relevant literature.

Abstract
This study utilized the mallard's foot as the subject, examining the bone distribution via computed tomography (CT) and analyzing pertinent parameters of the tarsometatarsal bones. Additionally, gross anatomy methods were employed to elucidate the characteristics of the toes and webbing bio-structures and their material composition. Biologically, the mallard's foot comprises tarsometatarsal bones and 10 phalanges, enveloped by fascia, tendons, and skin. Vernier calipers were used to measure the bones, followed by statistical analysis to acquire structural data. Tendons, originating in proximal muscles and terminating in distal bones beneath the fascia, facilitate force transmission and systematic movement of each segment's bones. Regarding material composition, the skin layer serves both encapsulation and wrapping functions. Fat pads, located on the metatarsal side of metatarsophalangeal joints and each phalanx, function as cushioning shock absorbers. The correlation between the force applied to the tarsometatarsal bones and the webbing opening angle was explored using a texture analyzer. A simplified model describing the driving force behind the webbing opening angle was introduced. Furthermore, we designed a bionic foot, contributing a foundational reference for anti-sinking bionic foot development.

Abstract
The advent of virtual reality (VR) in education offers unique possibilities for facilitating cooperative learning strategies, particularly in fields demanding intricate spatial understanding, such as gross anatomy. This study investigates the impact of integrating cooperative learning strategies within a VR-based gross anatomy curriculum, focusing on enhancing students' anatomy knowledge and skills. We analyzed the performance of two cohorts of first-year nursing students across five semesters (2016-2020), where traditional learning methods were used in the first three semesters (2016-2018), and a VR-based cooperative learning approach was adopted in the last two semesters (2019-2020). Our findings suggest that the VR-based cooperative learning group achieved significantly higher scores in their gross anatomy laboratory courses compared to their counterparts learning through traditional methods. This research provides valuable insights into how the integration of VR technology and cooperative learning strategies can not only enhance learning outcomes but also improve the VR learning experience by reducing motion sickness. It accentuates the potential of VR-based cooperative learning as an impactful educational tool in anatomy education. Future research should further explore the optimal integration of VR and cooperative learning strategies in diverse course types and their potential to enhance educational outcomes and the learning experience.

Abstract
This report describes the unique case of a completely patent Double Aortic Arch (DAA) combined with Kommerell Diverticulum (KD), absence of celiac trunk and congenital asplenia. The anatomical variants described were identified and assessed in a 51-year old female from a computed-tomography angiography (CTA) images with 3D-volume rendered reconstructions during her follow-up after hysterectomy. The reconstructed CTA images showed a DAA with the left common carotid artery stemming from the hypoplastic left aortic arch while the left subclavian artery originated from a KD in the descending thoracic aorta. A symmetric arrangement of the aortic arch branches was demonstrated, comprising a full vascular ring. Since the patient had been completely asymptomatic and with no symptoms of compression of the esophagus or trachea, no surgical management was advised. The abdomen CTA imaging revealed absence of the celiac trunk with direct origin of the common hepatic and the left gastric artery from the superior mesenteric artery as well as asplenia. We presented a case of asymptomatic DAA of completely patent arches with the right vertebral artery branching separately of and the left SCA originating from KD in the descending aorta. The term KD can be identified also in other arch anomalies than the one originally described. Since anatomical anomalies can be frequently combined, thorough imaging inspection with CTA of both thorax and abdomen is suggested.

Abstract
At Kansas City University, anatomy laboratories were delivered via remote (REM) or on-campus (OC) formats due to COVID-19, creating an opportunity to evaluate student perceptions of differences in laboratory delivery format. A six-item survey of Likert scale and open-ended questions explored the utility of anatomy software, prelab instruction handouts, and prosection reviews. Likert scale validity was analyzed using Cronbach's α; responses were compared among REM and OC formats using Chi-square. Descriptive codes were applied to summarize responses, which were grouped and converted into percentages. Statistically significant differences in REM versus OC formats were determined for the helpfulness of the prelab handouts (χ2 , 28.00; df, 4; p < 0.001) and effectiveness of cadavers in learning anatomy (χ2 , 20.58; df, 4; p < 0.0004). Trends in responses noted disagreement in the effectiveness of anatomy software (REM, 69.8%; OC, 51.08%), but agreement with the helpfulness of prosection reviews (REM, 85.9%; OC, 61.6%) (Cronbach α: REM, 0.648; OC, 0.646). Themes from narrative REM comments (n = 496) noted anatomy software was difficult to use (33.1%) and had issues with orientation (15.5%), as well as a student preference for OC laboratories (12.5%). The OC format responses (n = 456) noted poor software design (47.9%), unnecessary for studying (35.4%), and preference for in-person laboratories (7.4%). Qualitative analysis of narrative comments detailed other resources used, including Complete Anatomy™ and YouTube™. Trends highlighted the prelab handouts and prosection reviews for learning, the ineffectiveness of anatomy software, and a preference for OC laboratories. We highlight student perspectives of REM versus OC laboratory formats in response to COVID-19.

Abstract
The provision of distance education has increased rapidly over the past few years owing to the COVID-19 pandemic. The core of gross anatomy distance education is three-dimensional (3D) visualization of anatomical structures, and the use of simple 3D visualization tools has increased as distance education has become more popular. The purpose of this study was to establish a more effective operation plan in dental hygiene by investigating learners' opinions about distance education of gross anatomy and 3D visualization tools, and by comparing and analyzing their academic achievements. The study involved 250 students and comprised an analysis of 120 students who took a head and neck anatomy class at the Department of Dental Hygiene at D University via distance learning during 2020-2022, and 130 graduates who had completed the class via face-to-face learning during 2015-2017. An online survey of 120 of the enrolled students comprised 10 questions asking for opinions on the head and neck anatomy distance learning classes, five questions on the 3D visualization tool, and five on general characteristics. Overall, the learners had positive perceptions of distance education for head and neck anatomy and the 3D visualization tool. Among the education methods compared, they generally preferred blended learning (n = 47, 39.2%). There was a significant preference for the distance learning method of asynchronous classes (n = 86, 94.5%). Analysis of academic achievements according to whether or not distance education was conducted revealed a significantly higher score in the face-to-face class group (P < 0.05). A blended learning method can be effective in increasing learner satisfaction and improving academic achievement in gross anatomy classes on dental hygiene. It is suggested that theoretical material should be learned through asynchronous content and knowledge expanded through small-group activities during face-to-face learning. This will help establish a standard model for teaching of gross anatomy in dental hygiene in the postpandemic era.

Abstract
The posterior compartment of the leg typically contains three muscles in the superficial flexor group: the gastrocnemius, plantaris, and soleus. The gastrocnemius has medial and lateral heads (MH and LH) that originate from the medial and lateral condyles of the femur, respectively. However, a third head (TH) of the gastrocnemius, is a rare accessory muscle bundle of the gastrocnemius muscle that covers the surface of the popliteal fossa. Bilateral THs of gastrocnemius were identified in a 67-year-old male during a routine educational cadaveric dissection. Both gastrocnemius TH muscles consisted of a superficial belly with distinct neurovasculature heads and originated from the lateral condyle of the femur and inserted into the Achilles tendon. To our knowledge, the co-existence of bilateral gastrocnemius TH muscles has only been reported once. The male donor was found to exhibit an anatomical anomaly and could be clinically underdiagnosed due to its clinically silent nature and the lack of reports. Insight into the potential implications of bilateral and unilateral gastrocnemius TH and identification during clinical evaluation offers a path for future research to better identify and manage cases of gastrocnemius TH and its effects.

Abstract
The article covers aspects of morphological, anatomical, embryological, histological aspects and origin, types, blood supply, innervation, lymph drainage of human vermiform appendix. The purpose of the study is to understand real function and to summarize this information for positive impact on clinical decision in case of appendicitis. Although characteristic features of normal and diseased appendix have been reported for many previous centuries, it still the most common challenge facing every day in operation room. The appendectomy, commonest surgical emergency procedure, may cause little confusion in surgeons due to highly variable situations of it inside the abdominal cavity. However, the recent imaging techniques have increased ability of surgeon for crucial diagnosis of the diseased appendix.

Abstract
Physicians must be able to integrate knowledge across disciplines. Therefore, educators need to provide opportunities for students to cognitively integrate information across the medical school curriculum. Literature has shown that specifically pointing out these connections helps students create cause and effect models and ultimately improve their performance. The gross anatomy laboratory provides an excellent environment for students to integrate information by establishing structure and function relationships. This article presents simple steps to create modules which help students cognitively integrate physiology and anatomy at the session level in the gross anatomy laboratory. Driven by backward design, these steps include establishing objectives, creating assessments, and developing activities that can be implemented in a specific learning environment. An example of a flexible module which could be implemented in a number of gross anatomy lab settings (e.g., prosection, dissection, models, virtual) is presented along with a template for the design of future modules. This is followed by a discussion of challenges encountered by educators attempting to integrate structure and function in the gross anatomy lab. Each of these considerations will be addressed with potential solutions for educators seeking to implement these types of integrated activities.

Abstract
Louis Hubert Farabeuf (1841-1910) was a reformer of clinical, surgical, and topographic human anatomy studies during the second half of the 19th century. Over 30 years as a professor of Anatomy, Farabeuf wrote outstanding anatomical textbooks. As the head of Anatomic Studies in the Faculty of Medicine in Paris, he succeeded in leading a profound restructuring of the way anatomy and surgery were taught. As a result of his work and research, several anatomical terms, clinical signs, and surgical instruments were named after him. For his outstanding career in anatomy, he was elected to the Academy of Medicine in 1897.

Abstract
Traditionally, anatomy was one of the basic pillars of medical training. However, due to the expansion of medical science and medical knowledge in general, anatomy teaching has steadily declined and the way anatomy is taught has changed. These changes go hand in hand with growing literature about a perceived and proven lack of anatomical knowledge. While anatomy is important for all doctors, these developments seem to be more worrying for surgical residents. At the same time, little is known about how clinicians use anatomy in daily practice. The primary aim of this study was to increase understanding of the role of anatomy in the daily practice of gynecologists. An explorative qualitative study was performed to answer the question "What is the tangible utility of solid anatomical knowledge in the daily practice of the gynecologist"? Semi-structured interviews with gynecologists and obstetrics and gynecology (ObGyn) residents from Belgium and the Netherlands were held and the responses were analyzed using a phenomenographic inductive coding approach. Anatomical knowledge was important and used for technical skills and non-technical achievements in the daily practice of gynecologists, and three themes were distinguished. Specifically, anatomical knowledge was important and used (1) for daily activities, (2) for the feeling of self-efficacy, and (3) to gain a respected name as a doctor. These findings are discussed in light of (perceived) insufficient anatomical knowledge, and recommendations are made for the postgraduate education of ObGyn doctors.

Abstract
The last two decades have seen a shift in the way anatomy education is delivered. With the introduction of blended learning, cadaveric dissection is no longer the be all and end all and, in many cases, the continuing role of anatomical teaching artefacts has declined after decades of prominence. While some institutions have abandoned their archaic anatomical collections and medical museums completely, others have invested in their technological enhancement. We describe the integration of historical teaching artefacts into contemporary anatomy education through the development of an interactive online e-platform and shed light on the enduring pedagogic value of past anatomical teaching specimen.

Abstract
Students' reflective writings in gross anatomy provide a rich source of complex emotions experienced by learners. However, qualitative approaches to evaluating student writings are resource heavy and timely. To overcome this, natural language processing, a nascent field of artificial intelligence that uses computational techniques for the analysis and synthesis of text, was used to compare health professional students' reflections on the importance of various regions of the body to their own lives and those of the anatomical donor dissected. A total of 1365 anonymous writings (677 about a donor, 688 about self) were collected from 132 students. Binary and trinary sentiment analysis was performed, as well as emotion detection using the National Research Council Emotion Lexicon which classified text into eight emotions: anger, fear, sadness, disgust, surprise, anticipation, trust, and joy. The most commonly written about body regions were the hands, heart, and brain. The reflections had an overwhelming positive sentiment with major contributing words "love" and "loved." Predominant words such as "pain" contributed to the negative sentiments and reflected various ailments experienced by students and revealed through dissections of the donors. The top three emotions were trust, joy, and anticipation. Each body region evoked a unique combination of emotions. Similarities between student self-reflections and reflections about their donor were evident suggesting a shared view of humanization and person centeredness. Given the pervasiveness of reflections in anatomy, adopting a natural language processing approach to analysis could provide a rich source of new information related to students' previously undiscovered experiences and competencies.

Abstract
BACKGROUND The retro-oesophageal right subclavian artery (RRSA) is a congenital anomalous branching of the arch of the aorta. Because its incidence is very low, it has not been fully understood how the RRSA develops during embryogenesis, and thus accumulation of observed findings in newly found cases is important to elucidate the aetiology of the RRSA. MATERIALS AND METHODS We encountered a case of the RRSA during the course of gross anatomy dissection for medical students. RESULTS The main findings in the present observations are that (a) the RRSA arose from the right side wall of the arch of the aorta as its last branch; (b) the detected RRSA was directed to the right and upward between the oesophagus and vertebral column; (c) the right vertebral artery branched from the RRSA and entered the sixth cervical foramen transversarium; (d) the suprema intercostal artery branched from the costocervical trunk on both sides and its distal branches were distributed to the first and second intercostal spaces; and (e) both sides of bronchial arteries originated from the thoracic aorta. CONCLUSIONS The present study gives further information about the morphological details of the RRSA leading to better understanding of its developmental process.

Abstract
An understanding of forearm and wrist anatomy is necessary for the diagnosis and treatment of various injuries. Evidence supports the use of peer-assisted learning (PAL) as an effective resource for teaching basic science courses. First-year medical students across three class years participated in an optional PAL kinesthetic workshop wherein participants created anatomically accurate paper models of forearm and wrist muscles. Participants completed pre- and post-workshop surveys. Participant and nonparticipant exam performances were compared. Participation ranged from 17.3% to 33.2% of each class; participants were more likely to identify as women than men (p < 0.001). Participants in cohorts 2 and 3 reported increased comfort with relevant content after the workshop (p < 0.001). Survey responses for cohort 1 were omitted due to low response rates; however, exam performances were assessed for all three cohorts. Cohort 2 participants scored higher than nonparticipants on forearm and wrist questions on the cumulative course exam (p = 0.010), while the opposite was found for cohort 3 (p = 0.051). No other statistically significant differences were observed. This is the first study to examine quantitative and qualitative results for a PAL intervention repeated for three separate cohorts. Although academic performance varied, two cohorts reported increased comfort with relevant course material after the workshop. Results of this study support the need for further exploration of PAL workshops as an instructional method in teaching anatomy and highlight the challenges associated with repeating interventions over multiple years. As more studies attempt replication across multiple years, these challenges may be addressed, thereby informing PAL best practices.

Abstract
Anatomical body painting has traditionally been utilized to support learner engagement and understanding of surface anatomy. Learners apply two-dimensional representations of surface markings directly on to the skin, based on the identification of key landmarks. Esthetically satisfying representations of musculature and viscera can also be created. However, established body painting approaches do not typically address three-dimensional spatial anatomical concepts. Haptic Surface Painting (HSP) is a novel activity, distinct from traditional body painting, and aims to develop learner spatial awareness. The HSP process is underpinned by previous work describing how a Haptico-visual observation and drawing method can support spatial, holistic, and collaborative anatomy learning. In HSP, superficial and underlying musculoskeletal and vascular structures are located haptically by palpation. Transparent colors are then immediately applied to the skin using purposive and cross-contour drawing techniques to produce corresponding visual representations of learner observation and cognition. Undergraduate students at a United Kingdom medical school (n = 7) participated in remote HSP workshops and focus groups. A phenomenological study of learner perspectives identified four themes from semantic qualitative analysis of transcripts: Three-dimensional haptico-visual exploration relating to learner spatial awareness of their own anatomy; cognitive freedom and accessibility provided by a flexible and empowering learning process; altered perspectives of anatomical detail, relationships, and clinical relevance; and delivery and context, relating to curricular integration, session format, and educator guidance. This work expands the pedagogic repertoire of anatomical body painting and has implications for anatomy educators seeking to integrate innovative, engaging, and effective learning approaches for transforming student learning.

Abstract
In recent years, the logistical challenges posed by the Covid-19 pandemic have prompted medical educators teaching gross anatomy to explore an expanded use of online instructional modalities. There is concern that this shift to online anatomy education in medical schools could affect long-term learning outcomes for future healthcare providers. In this systematic review, the educational effectiveness of online anatomy teaching is compared with traditional ("face-to-face") teaching methods, specifically in terms of students' academic performance and satisfaction. A search of four databases identified and screened 162 studies. Subsequently, 31 studies were analyzed, including both (a) teaching outcome measures (test scores) and (b) student satisfaction ratings. Authors chose studies, extracted data, assessed quality and examined risk of bias. Nineteen studies compared students' academic performances between online and face-to-face teaching methods. Twenty-six studies measured students' levels of satisfaction in both teaching methods. Both qualitative and quantitative analyses of the data revealed comparable academic performances with no statistical difference between the two teaching methods, but a higher level of satisfaction with face-to-face teaching. The findings confirm that students can learn from online teaching but are more satisfied with face-to-face teaching. The authors conclude that online teaching cannot replace traditional teaching and there is no preference for one type of modality over the other. Therefore, a multi-modal learning approach combining online with face-to-face educational modalities for medical students could be efficient and successful.

Abstract
Prior to the challenges imposed by the Covid-19 pandemic, anatomy practical sessions at Trinity College Dublin involved eight to 10 students per donor station, rotating between digital learning, anatomical models/osteology, and dissection activities for three hours weekly. To maintain cadaveric participation in the anatomy laboratory while adhering to distancing guidelines, a transition to dyad pedagogy was implemented. This mode of delivery allowed two students per donor station to spend one hour per week in the anatomy laboratory with all digital learning elements transferred to the virtual learning platform Blackboard as pre- and post-practical session learning activities. Dyad pedagogy has been explored in clinical settings and simulation procedural-based training but is yet to be fully verified in anatomy education. To determine the effectiveness of hybrid practical sessions and reduced donor to student ratios, the opinions of first year medical students were examined using an online questionnaire with a 51% response rate. Although students recognized the merits of more time in the anatomy laboratory, including opportunities for self-directed study and exposure to anatomical variation, they felt that having two students per station enabled sufficient hands-on time with the donor body and fostered learning opportunities that would not be possible with larger groups. Strong preferences for quality time with the donor body supported by online resources suggests this modality should be a key consideration in course design for anatomy curricula and emphasizes the importance of gauging students' preferences to optimize satisfaction and learning output when pivoting to blended learning strategies in anatomy education.

Abstract
BACKGROUND One of the greatest developments in modern medicine is the strides taken in radiology. Today, thanks to high-tech devices like computer tomography (CT), magnetic resonance imaging (MRI), and ultrasound, a noninvasive glimpse into the human interior has been made possible. These recent developments have revolutionized how doctors see anatomy. To keep pace with this progress, many medical school anatomy curriculums have undergone a facelift. In these new curriculums, radiology has been presented as a practical and sufficient alternative tool for learning anatomy. This study, therefore, aimed to determine the extent of the use of radiologic images in the teaching of anatomy in Ethiopian medical schools. METHODS An online questionnaire was used to collect, compile and analyze data from anatomy instructors in Ethiopian medical schools. RESULTS The survey showed that 55.9% of the instructors used radiologic images of one form or another in their teaching. However, it also revealed radiological images comprise <5% of the total images used in teaching. The majority (73.5%) of the instructors lacked any prior training or coursework in radiologic anatomy. Despite full-time radiology faculties existing in the schools, a relationship between the anatomy and radiology department is virtually unheard of. CONCLUSION The curriculum currently in use in Ethiopian medical schools is designed in a way both vertical and horizontal integration of the traditional subjects are achieved. This way, the introduction of clinical medicine early will provide context and relevance to the learning of basic science. Despite the curriculum's emphasis, we have observed limitations in the degree of integration of anatomy and radiology.

Abstract
Although formaldehyde is the most widely used and largely available fixative for preserving cadavers through decomposition prevention, it promotes darkening and weight gain, in addition to being considered carcinogenic. Ethyl alcohol has been proven a potential substitute to formaldehyde due to its effectiveness in tissue penetration, thus preventing proliferation of microorganisms; however, it can only be used alone for fixation of small parts. In view of such fixatives limitations, saturated salt solution has been widely employed based on its antimicrobial effect and ability to maintain tissue similar to the original one, in addition to exerting no hazardous effects as there is no evaporation of harmful substances. This research aimed to observe anatomical brain behaviour submitted to formaldehyde, alcohol, and saturated salt solution as fixatives. Fixatives were tested in 15 adult Wistar rats' brain, submerged in 10 ml of intended solution after removal for 4 weeks. Weight of the brains fixed in saturated salt did not change over the weeks. However, the weight of formaldehyde-fixed brains increased and the weight in alcohol-fixed brains decreased; in addition, modifications in all solutions measures were also observed. Alcohol provides a peculiar dehydrating effect as formaldehyde clearly increases the length of the pieces. Thus, since the saturated salt solution showed no important adjustment over the experimental time, it proved an efficient alternative for replacing formaldehyde and alcohol as fixative solutions of anatomical study of the brain.

Abstract
The knowledge of anatomy and imaging exams emerges as an important tool in the study of evolutionary processes of a species, in the elaboration of diagnosis, and the successful choice of the appropriate clinical and surgical procedures. Therefore, this study aims to describe the osteology of the hind limb of Sapajus libidinosus by means of gross, radiographic, and tomographic images. Four cadavers were used in the macroscopic analysis and five animals for the imaging exams, of which four were eventually euthanized and added to the macroscopic study. For imaging exams, they were kept anesthetized. All bones of the hind limb were documented, their structures were described, and compared with data in the literature from human and nonhuman primates. We have performed Student's t test for independent samples. There was no statistical difference between the sexes regarding the length of the hind limb bones. The coxal bone was largely well described using imaging methods. A small penile bone was present at the tip of the penis and it could be identified by all analysis methods. The femur, as well as the tibia and fibula, were not well portrayed in their proximal and distal epiphyses by radiography (Rx). However, they were well identified on tomography. No third trochanter was observed in the femur and the patella had a triangular shape. All the structures described by gross anatomy of the tarsus and metatarsus could be identified by Rx and tomography. More subtle structures, such as the popliteal notch on the tibia, and the gluteal tuberosity pectineal line and facies aspera on the coxal bone, were not identified by medical imaging. S. libidinosus presented anatomical characteristics that were similar to those of larger New World and Old World monkeys, including man. This suggests it's value as an experimental model for studies in recent primates.

Abstract
Medical students' motivation and study strategies are crucial in determining academic performance. This study aimed to assess the motivation and learning strategies of medical students as well as their association with performance in anatomy examinations. The Motivated Strategies for Learning Questionnaire, two focus group discussions, and students' current anatomy cumulative grade point average (cGPA) were used. Generally, the medical students strongly felt that anatomy is fundamental to the practice of medicine and surgery. This result was consistent with high task value scores of 5.99 ± 1.25. They were also driven by extrinsic goal orientation (5.59 ± 1.42) and intrinsic goal orientation (5.08 ± 1.26). Most medical students typically relied on elaboration (5.35 ± 1.25) ahead of other cognitive strategies namely rehearsal (5.30 ± 1.11), organization (5.15 ± 1.34), and lowest-rated critical thinking (4.77 ± 1.19). The students also relied on resource management strategies, effort regulation (5.15 ± 1.20) and time and study environment regulation (5.03 ± 1.03) more than the moderately scored peer learning (4.95 ± 1.50) and help-seeking (4.95 ± 1.09). In the focus group discussions, students reported that they often narrate or explain to each other what they would have read and understood from anatomy lectures, tutorials, and textbooks. They also bemoaned the lack of institutional support for stress burdens. The motivation and learning strategies subscales were not correlated with anatomy cGPA. Males were driven by extrinsic goals and experienced significantly higher levels of test anxiety than females (P < 0.05). Knowing the motivation and learning strategies students employ early in the medical curriculum can be leveraged to promote self-directed learning and academic achievement.

Abstract
The training for pancreatic surgery still is not conducted according to standardized protocols, and academic programs differ between countries and hospitals. Moreover, due to recent technological innovations such as minimally invasive and robotic surgery, and the broader indications for complex pancreatic procedures due to the use of neoadjuvant chemotherapy, training is continuously redefining itself. The historical paradigm of "see one, do one, teach one" has been challenged and might have become obsolete. Finally, the rising number of surgical residents along with the limited time required practicing during residency might represent a major limitation to becoming an independent surgeon. Gross anatomy is a solid practice for the active learning of human anatomy during medical school. With regards to the pancreas, it offers a unique opportunity to both actively study the pancreatic gland anatomy during dissection and simulate actual surgical procedures. A critical review of the literature was conducted, aiming to assess the role of gross anatomy in surgical training and possible future perspectives.

Abstract
It is critical that academic opinion of pandemic pedagogy is comprehensively quantified in order to inform future practices. Thus, this study examines how anatomists in the United Kingdom (UK) and Republic of Ireland (ROI) perceive the teaching adaptations made in response to COVID-19, and how these adaptations have impacted their experiences teaching, their online work environment and community. Data was collected via a questionnaire from 24 anatomists across 15 universities in the UK (11) and ROI (4). With regards to teaching, 95.6% of academics have upskilled in new technologies to meet the demands of distance teaching. Academics (95.8%) preferred face-to-face delivery of practical sessions. Most universities (80.0%) reported that practical sessions will continue in a new form that ensures social distancing. However, 50.0% of academics are uncertain if these adaptations will improve student learning. Many anatomists believe that the new adaptations may hinder student-student (66.7%) and student-tutor (45.8%) interactions. Regarding assessment, 52.6% of academics preferred traditional methods to online. Remote online assessment was difficult to protect against collusion, but provided time saving opportunities for academics. Finally, in terms of working environment, 83.3% of academics stated that their workload increased; 54.2% preferred working on site rather than remotely and 79.2% think that staff interactions are better when working on site. These results demonstrate a widespread concern amongst anatomists regarding the pandemic-induced adaptations to teaching, assessment and working environment. However, important opportunities were also identified that could ultimately serve to benefit students and educators alike.

Abstract
The present work was the first attempt to examine the oesophagus and stomach of the Eurasian common moorhen grossly and by SEM. The oesophagus was composed of long cervical and short thoracic parts. The longitudinal folds of the cervical part were narrower than that of the thoracic part, while the depressions between these folds were shallower and wider in the cervical part. On the epithelial surface of the oesophagus, micropapillae were present and they were numerous and smaller at the level of the cervical part. The openings of the oesophageal glands were circular at the level of the cervical part and oval to elliptical at the thoracic part. The crop was absent. The proventriculus was fusiform in shape; its mucosa was arranged in several, concentrically arranged mucosal folds connected with each other by transverse folds. The proventriculus glands were oval and opened by raised papillae on the epithelial surface. The gizzard was oval; its mucosa was lined by a horizontal layer of cuticle appeared like the fish scales, while the vertical part of the cuticle appeared as thin rods. The folds of the oesophagus are functioning for the expansion for the passage of the food particles. The tunica musculosa of the gizzard was thick to help in grinding of the food particles.

Abstract
Assessment of the lymph nodes is key in staging cancer patients. Descriptions of normal features of the feline lymph nodes using computed tomography (CT) and ultrasound (US) are limited. A prospective anatomic and comparative imaging study was performed. The frequency of identification and the size of the lymph nodes during gross pathology from 6 feline cadavers were compared to the images of lymph nodes from 30 presumed healthy adult cats obtained by CT and US. Measurements (length, width, and height) were compared among techniques. The CT and US features of the identified lymph nodes were also recorded. The frequency of identification of the lymph centers varied among techniques and individually. The mandibular lymph nodes were identified in 100% of the cadavers and in 100% of the healthy cats using CT and US. The medial retropharyngeal lymph nodes were identified in 100% of the cats using CT and US. The deep cervical lymph nodes were not visualized in the cadavers. The cranial mediastinal and tracheobronchial lymph nodes were not visualized using US. Lymph nodes showed a higher length on CT and higher width on US. The height was the most statistically significant variable measurement among techniques. On CT, lymph nodes were most frequently isoattenuating or slightly hypoattenuating to surrounding musculature, with homogeneous contrast enhancement. On US, most lymph nodes were isoechoic or hypoechoic to surrounding fat tissue. The lymph nodes were most frequently elongated or rounded.

Abstract
The current study aimed to describe the normal gross anatomy, computed tomography (CT) and magnetic resonance imaging (MRI) of the metacarpo/metatarsophalangeal (MCP/MTP) joint in Egyptian buffalo, and to determine the site of intra-articular injection of this joint. This study was conducted on eighteen fresh cadaveric distal limbs of healthy Egyptian buffaloes. Six cadaveric MCP/MTP joints were freshly dissected for studying their normal morphological features and determination of the suitable site for intra-articular injection. Another twelve MCP/MTP joints were imaged using a 16-slice CT scanner and a 1.5 Tesla MRI scanner, injected with coloured latex and then sectioned into dorsal, sagittal and transverse slices. The articular surface, joint cavity, ligaments and surrounding tendons of the MCP/MTP joint were identified and briefly described. CT and MRI provided identification of the bony and soft tissue structures of the MCP/MTP joint with variable signal intensities. The present study provided a brief description of the normal gross anatomy of MCP/MTP joint in buffalo to serve as a reference for the evaluation of CT and MRI images, which in turn could enable the veterinary clinicians in interpretation of the clinical diseases in this joint.

Abstract
Background: The prevalence of overweight and obesity continues to rise and is associated with increased morbidity and mortality. Weight bias is common among physicians and medical students and limits the therapeutic alliance between providers and patients with overweight and obesity.Objective: The authors sought to explore the relationship between the gross anatomy course and medical student attitudes towards weight and obesity.Design: The authors employed a mixed-methods approach consisting of semi-structured interviews and anonymous web-based surveys of first-year medical students taking gross anatomy at one USA medical school. They analyzed transcripts of interviews and free-text survey responses using a grounded theory approach and performed tests of association to investigate the relationship between demographic information, responses to multiple-choice survey questions and weight bias.Results: A total of 319 (52%) first-year medical students (2015-2018) completed the survey and 33 participated in interviews. Of survey respondents, 71 (22%) responded that the course had changed how they felt about people with overweight/obesity. These respondents were also more likely to affirm that the course had affected their views toward their own bodies (p < 0.001). Qualitative data analysis identified three overarching themes within students' descriptions of the effects of the gross anatomy lab on attitudes toward bodies perceived to have excess weight: these bodies were described as 1) difficult, 2) unhealthy, and 3) evoking disgust. Students extrapolated from their experiences with cadavers to imagined interactions with future patients, relying heavily on the narrative of the difficult patient.Conclusions: At one USA medical school, students perceived their experiences in gross anatomy as shaping their attitudes toward individuals with overweight or obesity. Efforts to reduce medical student weight bias ought to target this previously unexplored potential site of weight bias.

Abstract
Background Two types of stress, bending stress and traction stress, have been reported to be involved in the mechanism of Jones fracture. However, little is known about the risk factors for traction stress. Purpose To classify the attachment position of the peroneus brevis muscle (PB), peroneus tertius (PT), lateral band of the plantar aponeurosis (LB), and the long plantar ligament (LPL), focusing on the zone where a Jones fracture occurs (zone 2), and to compare the footprint area of each tissue type. Study Design Descriptive laboratory study. Methods This study examined 102 legs from 55 Japanese cadavers. Type classification was performed by focusing on the positional relationship between each tissue attachment and the zone where Jones fracture occurs (zone 2). The classifications were as follows: type I, attached proximal to the border between zones 1 and 2; type IIa, attached to the border between zones 1 and 2 with one attached part; and type IIb, attached across the border between zones 1 and 2 with two or more attached parts. The footprint areas of the PB, PT, LB, and LPL were compared between tissue types and within each attachment classification. Results The PB was recorded as type I in 41 feet (40.2%), type IIa in 56 feet (54.9%), and type IIb in 5 feet (4.9%); the PT was recorded as type IIa in 54 feet (60.0%) and type IIb in 36 feet (40.0%); and the LB was recorded as type I in 27 feet (26.5%) and type IIa in 75 feet (73.5%). The LPL did not attach to the fifth metatarsal bone. No significant difference was found in the footprint area between type I PB and type I LB. Conclusion The results indicate that type I, which attaches proximal to zone 2, occurs with PB and LB, and there was no significant difference in the footprint area between them. These findings suggest that type I is involved in traction stress. In the future, biomechanical research based on the results of this study will be necessary. Clinical Relevance The results of this study provide basic research for investigating the mechanism of Jones fracture and the cause of delayed healing.

Abstract
BACKGROUND It is critical for surgeons to have a full understanding of the complex courses and ramifications of the human internal iliac artery and its parietal branches. Although numerous anatomical studies have been performed, not all variations at this site are currently understood. Therefore, we characterised these blood vessels in foetal pigs to provide additional insight from a comparative anatomical perspective. MATERIALS AND METHODS Eighteen half-pelvis specimens from foetal pigs were dissected and examined on macroscopic scale. RESULTS Among our findings, we identified the internal iliac artery as a descending branch of the abdominal aorta. A very thick umbilical artery arose from the internal iliac artery. The superior gluteal, inferior gluteal, and internal pudendal arteries formed the common arterial trunk. Although the superior gluteal artery emerged from the common trunk from inside the pelvis, the inferior gluteal and internal pudendal arteries bifurcated at deep layer within the gluteus muscles after leaving pelvic cavity. We were unable to detect an typical obturator artery emerging from the internal iliac artery. A branch supplying the hip adductors was identified as arising from the inferior epigastric artery which itself was derived from the distal end of the external iliac artery. CONCLUSIONS We identified the anatomic characteristics of the internal iliac artery and its parietal branches in the foetal pig. Our findings provide new insight into the comparative anatomy of the internal iliac artery and will promote understanding of related morphogenetic processes.

Abstract
The arterial supply of the cat jejunum was studied by gross dissection and polyurethane corrosion cast. The results showed that the jejunal arteries, which originate from the cranial mesenteric artery, varied from 5 to 15 in number. Their number was independent of the length of the cranial mesenteric artery as well as of the length of the jejunum. These arteries divided into branches giving rise to a series of orders of division from a minimum of 1 to a maximum of 7. The last orders of division terminated in a series of anastomosing arcades which resulted in a marginal artery coursing only a few millimeters from the mesenteric margin of the jejunum. This artery gave rise to straight arteries (vasa recta), whose mean number was 450 ± 60. According to their length, the vasa recta can be differentiated into short (vasa brevia) and long (vasa longa) branches. The vasa brevia ended branching into the mesenteric side of the jejunum whereas the vasa longa coursed beneath the serosa on the lateral jejunal surfaces, and reached the antimesenteric border. During their course, the vasa recta ramified and anastomosed with each other. Numerous antimesenteric anastomoses between opposing vasa longa were also observed. Based on the literature consulted, due to the large number of vasa recta (approximately one vessel per 2.9 mm of jejunal length) and the rich anastomotic network, the cat jejunum might have a better intramural distribution of blood flow and would seem less predisposed to ischemic phenomena than that of other mammals.

Abstract
Clinical skills and medical knowledge enable physicians to overcome the uncertainty of emergent and rare clinical scenarios. Recently, a growing emphasis on evidence-based medicine (EBM) has flooded medical curricula of universities across the globe with guideline-based material, and while it has given teachers and students new tools to improve medical education, clinical reasoning must be reaffirmed in its capacity to provide physicians with the ability to solve unexpected clinical scenarios. Anatomical education in medical school should have two main objectives: to acquire anatomical knowledge and to develop the skill of applying that knowledge in clinical scenarios. The authors present a clinical scenario in which an unexpected and rare complication occurred during a routine elective hip replacement surgery. The general surgeon presiding over the case, also an anatomy professor, solved the problem using clinical reasoning and anatomical knowledge. It was a clear example of how clinical reasoning is key in approaching unprecedented, rare, or unknown complications. The intention of this scenario is to remind colleagues and medical schools that, although EBM is the standard, educators must uphold sound clinical reasoning to best prepare health care providers for their careers.

Abstract
Discussion is ongoing concerning the need to ensure the clinical relevance of the biomedical sciences. However, clinical relevance within health care courses presupposes that there is internationally agreed core material to be taught and learned. For anatomy, by the initial use of Delphi Panels that comprise anatomists, scientists, and clinicians, the International Federation of Associations of Anatomists (IFAAs) is developing internationally accepted core syllabuses for all anatomical sciences disciplines in the health care professions. In this article, the deliberations of a Delphi Panel for the teaching of thoracic anatomy in the medical curriculum are presented, prior to their publication on the IFAA's website. To develop the syllabus further, it is required that anatomical societies, as well as individual anatomists and clinicians, comment upon, elaborate, and amend this draft recommended syllabus. The aim is to set internationally recognized standards and thus to provide guidelines concerning the knowledge of the human thorax expected of graduating medical professionals. Such information should be borne in mind by those involved in the development of medical courses. Clin. Anat. 33:300-315, 2020. © 2019 Wiley Periodicals, Inc.

Abstract
This study aimed to describe the gross anatomy of the ventral rami of the thoracic spinal nerves in capuchin monkey (Sapajus apella) and compare with humans and other primate species. Eight specimens, prepared in 10% formalin solution and dissected following routine standard techniques, were used. The animals presented 13-14 pairs of thoracic spinal nerves emerging from the intervertebral foramen and divided into dorsal and ventral rami. The ventral rami of the first 12 or 13 pairs represented intercostal nerves and the latter referred to the subcostal nerve. The intercostal and subcostal nerves gave off muscular and cutaneous branches (lateral and ventral), which promote innervation of muscles and skin associated with the chest and abdominal wall. Atypical anatomy was verified for the 1st, 2nd and 7th to 13th intercostal nerves as well as for the subcostal nerve. The morphological characteristics were similar to those observed in humans and some non-human primates, especially in the absence of collateral branches.

Abstract
Background Physiotherapists know the depth of gross anatomical knowledge required for safe and effective clinical practice. They can offer insightful opinions on inclusions for and teaching of an anatomy curriculum for physiotherapy students. Objectives The aim of this study was to gather opinions of physiotherapists as to what they perceive as necessary anatomy curricular content for undergraduate physiotherapy students and identify pedagogy that should be used. Method A qualitative methodology using a grounded theory approach incorporating semi-structured interviews was utilised in this study. Theoretical sampling was used to identify representative South African physiotherapists. An inductive process, using continuous manual analysis of data by two independent coders, was undertaken. Data were collapsed until themes were identified. Triangulation and other strategies for trustworthiness of data were instituted. Results Theoretical saturation was reached after five focus groups (n = 32). Demographical information indicated physiotherapists of all age groups and both genders working in diversified clinical areas. Seven themes were identified and incorporated information from ‘structure’, ‘content’ and ‘pedagogy’ for anatomy programmes to the psychological impact of course aspects on a student’s psyche. Vertical integration of anatomy into later preclinical years, incorporation of physiotherapists to teach anatomy, a ‘physiotherapist personality’ and ‘anatomy know how’ for clinical practice were included. Conclusion Opinions of physiotherapists are important in identifying curricular and teaching considerations that can be incorporated into an anatomy programme designed for physiotherapy students. Clinical implications Targeted anatomy education for physiotherapy students can aid learning and retention of anatomical knowledge necessary for effective and safe clinical practice.

Abstract
While most German anatomy institutes provide only limited information about body donors and their lives, students have expressed a desire to learn more about these individuals, especially about their motivations to donate their bodies for the sake of medical education. In order to gratify this wish, as well as to further humanize body donors, an educational film was compiled, and a study designed to capture the film's effects on medical students. This is the first study using standardized, validated psychological tools to evaluate the impact of an educational film about body donors on students' empathy and psychological stress levels. The study followed a longitudinal, controlled, and cluster randomized design, including 77 (48 females/29 males) participants who watched the video either before, midway, or after the dissection course. Questionnaires were completed at four points in time applying the Jefferson Scale for Empathy (JSPE-S) and the Interpersonal Reactivity Index (IRI) to measure empathy. Psychological stress levels were recorded by the Brief Symptom Inventory (BSI). Overall, students recommended the film to be shown to all students (median 6.0; maximum on the six-point Likert scale). Viewing the film revealed no significant changes between study groups or over time in JSPE-S sum scores. All groups demonstrated a significant reduction of BSI values before the dissection course actually started and increased values during the course, but both developments appeared not to be associated with the intervention. Overall, the educational film did not correlate with any negative effects on students' empathy and psychological stress levels, and it was strongly approved of by students, as it provided more humanizing personal information about body donors without violating their anonymity.

Abstract
Superficial head and neck vessels are increasingly used in surgical procedures and are especially important in facial transplantation surgeries. We report a variant course of the submental vein observed during a dissection of a 79-year-old-male embalmed cadaver: a left submental vein running caudally across the intermediate tendon of the digastric muscle, separating from the course of the submental artery and emptying directly into the common facial vein in the carotid triangle. Such course may complicate submental island flap harvesting, as well as the graft manipulations and reattachment, since the vein could be damaged during the conventional procedure. This report therefore extends current knowledge of the variations of the vascular anatomy of the head and neck.

Abstract
OBJECTIVES The round window membrane (RWM) is small in size, making it difficult to clarify its shape and structure. The authors examined a 40x magnified 3-dimensional model of the human RWM to clarify its morphologic aspects and characteristics. METHODS An RWM specimen was obtained from an archival, formalin-fixed, decalcified, left temporal bone of an 84-year-old female cadaver. The data obtained by laser scanning microscopy were input into a 3-dimensional printer. After a model of the RWM was created, the following features were examined: striae on the surfaces, curvatures, thickness, and areas. Cross sections of the original specimen were made for histological observations. RESULTS The contour of this RWM model was approximately elliptic, with a saddle shape. When illuminated from the scala tympani side, the surface facing the fossula exhibited dark anterior and clear posterior portions. A borderline appeared where the 2 portions were bound along the short axis of the ellipse. This borderline was identified as the line of inflection. Collagen fibers were shown to run parallel to the borderline in the posterior portion but were fanned out in the anterior portion. CONCLUSIONS The magnified 3-dimensional model clarified gross anatomy and characteristics of the RWM. It is good teaching material for small tissues, such as the RWM.

Abstract
The first edition of the Terminologia Anatomica was published in 1998 by the Federative Committee for Anatomical Terminology, whereas the second edition was issued in 2011 by the Federative International Programme for Anatomical Terminologies. Since then many attempts have been made to revise and extend the official terminology as several inconsistencies have been noted. Moreover, numerous crucial terms were either omitted or deliberately excluded from the official terminology, like sulcus popliteus and diaphragma urogenitale, respectively. Furthermore, several synonyms are to be discarded. Notwithstanding the criticism, the use of the current version of terminology is strongly recommended. Although the Terminologia Anatomica is open to future expansion and revision, every change should be made after a thorough discussion of the historical context and scientific legitimacy of a given term. The anatomical nomenclature must be as simple as possible but also precise and coherent. It is generally accepted that hasty innovation ought not to be endorsed. Therefore, there is a need to take a closer look at these new proposals as they have been presented in numerous dispersed papers. This article provides an overview of these issues and concentrates on selected revisions and extensions that are didactically and clinically useful, thereby summarising the salient aspects of these new and compelling proposals.
