Leung Y, Ho KL, Yung L, Tang MKF. Reimagining human dissection in preclinical medical education using studio-based learning: A retrospective pilot study. ANATOMICAL SCIENCES EDUCATION 2024. [PMID: 38415402 DOI: 10.1002/ase.2386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/14/2024] [Accepted: 01/17/2024] [Indexed: 02/29/2024]
Abstract
Human dissections in the current medical curriculum are conducted using a checklist approach to prioritize the exposure of anatomical structures. In this setting, anatomy educators are labored to enhance their engagement during the dissection. To address this issue, we considered the current medical education pedagogies and identified a novel approach of studio-based learning (SBL) for application in a Human Dissection Workshop. This study aimed to (1) evaluate students' perceptions of SBL, (2) appraise the impact of SBL on anatomical knowledge learning, and (3) interpret the results of a validated questionnaire. Workshop participants were recruited from Year 2 medical students at the Chinese University of Hong Kong from the 2020 and 2021 cohorts. Fifty-one students participated in the workshop (N = 24 [2020], N = 27 [2021]), and 50 of them completed the postworkshop questionnaire rated on a 5-point Likert scale. Nineteen items were validated using a factor analysis. The interpretation of the questionnaire results demonstrated the different learning outcomes of the workshop, which included (1) enhancing students' knowledge and spatial understanding of anatomical structures, (2) strengthening students' appreciation of gross pathologies and clinical relevance, and (3) promoting higher-order thinking skills. To our knowledge, this is the first study to introduce SBL in medical education. The successful implementation of the workshop reflects the promising potential of SBL for enhancing human dissection and supplementing the medical curriculum.

Abstract
Purpose In 2018, the Michigan State University College of Human Medicine incorporated two-stage examinations into the gross anatomy curriculum. Multiple studies have investigated two-stage examinations and have largely reported positive findings. Here, we used a mixed-methods approach to further investigate the feasibility and student perceptions of the two-stage examination in the context of a medical school curriculum that emphasizes longitudinal group-based learning and formative assessments. Methods Three student cohorts were assessed with a formative two-stage examination at the end of their first-year anatomy experience. Data for the quantitative analysis included examination scores from the individual and group portions of the two-stage examination. For the qualitative stage of this project, we utilized a constructivist grounded theory methodology in which data, including both post-examination survey results and one-on-one semi-structured student interviews, were transcribed (interviews), coded, inductively and iteratively reviewed, and thematically interpreted. Results Survey and interview results revealed an overwhelmingly positive perception of the collaborative assessment experience. Student comments demonstrated educational value in the immediate feedback provided by this examination format and suggested that collaboration during the examination transformed the assessment into a learning experience. Conclusions While two-stage examinations have the potential to positively transform an assessment into a learning experience, we also identified complex relationships between content knowledge and anxiety that may affect student perceptions. In addition, examination logistics (e.g., curricular timing) have the potential to negatively affect student perceptions, indicating that faculty should consider these factors when implementing collaborative assessments into their curriculum.

Liao ML, Yeh CC, Lue JH, Lai IR, Chang MF. Impact of modified teaching strategies used in a gross anatomy course on the academic performance of dental students during the COVID-19 pandemic. EUROPEAN JOURNAL OF DENTAL EDUCATION : OFFICIAL JOURNAL OF THE ASSOCIATION FOR DENTAL EDUCATION IN EUROPE 2023; 27:1077-1087. [PMID: 36976652 DOI: 10.1111/eje.12901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 02/13/2023] [Accepted: 03/11/2023] [Indexed: 06/18/2023]
Abstract
INTRODUCTION Modified teaching strategies (MTS), asynchronous online teaching and smaller dissection groups, were applied to a gross anatomy course for dental students in the National Taiwan University in April 2020 in response to the COVID-19 pandemic. This study aimed to investigate the effects and perceptions of MTS on dental students. MATERIALS AND METHODS Scores for anatomy examinations for 2018-2019 (without MTS) and 2019-2020 (with MTS) cohorts were compared to explore the effect on academic performance. Moreover, questionnaire from the 2019-2020 cohort was analysed to determine dental students' perceptions about MTS. RESULTS The lecture performance in the final examination of the second semester for the 2019-2020 cohort was significantly higher than that of the first semester (pre-COVID-19) and that for the 2018-2019 cohort. However, the laboratory performance in the midterm examination of the second semester for the 2019-2020 cohort was significantly lower than that for the 2018-2019 cohort and showed no difference in the final examination of the first semester. The questionnaires revealed that the majority of students displayed positive attitudes towards MTS and agreed with the importance of peer discussion during laboratory dissection. CONCLUSIONS Asynchronous online learning for anatomy lecture may be beneficial for dental students; however, a smaller dissection group accompanied by reduced peer discussion may temporarily exert negative effects on their laboratory performance at the beginning of the application. Furthermore, more dental students exhibited positive perceptions towards smaller dissection groups. These findings could illuminate the learning condition of dental students in anatomy education.

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
Many new methods have contributed to the learning of anatomy, including several interactive methods, increasing the effectiveness of educational programs. The effectiveness of an educational program involving several interactive learning methods such as problem-based learning and reciprocal peer teaching was researched in this study. A quasi-experimental before-after study on three consecutive groups of second-year students at the Grenoble School of Medicine was conducted. The lectures were replaced by an educational program based on the problem-based learning method and reciprocal peer teaching. The first session was dedicated to reading clinical cases illustrating the medical concept, so that the learning objectives for the second session could be set. Then, after viewing digital courses, the second session was dedicated to a synthetic presentation by the students themselves, followed by an interactive summary with the teacher. The analysis of 630 students showed a significant increase in the theory test results for those who took part in the intervention: 9.71 versus 9.19 (β = 0.57, P = 0.036). Moreover, satisfaction was high after the intervention (mean = 4.5/5), and when comparing the two pedagogical approaches the students showed a clear preference for the program implemented with the concepts highlighted such as interactivity, in-depth work, group work, and autonomy. A multifaceted interactive pedagogy program could have a significant impact on the results of the theoretical concepts presented and on satisfaction as well as increased investment by students in learning anatomy.

Abstract
BACKGROUND Delivering sufficient otology education for undergraduates is known to be difficult, with limited teaching time being a contributing factor. Increasing student access to dissections of the ear could serve to increase satisfaction with teaching at St George's, University of London, UK. OBJECTIVE To evaluate student satisfaction with clinical ear anatomy teaching and investigate whether it can be improved using dissected specimens. METHOD Participants completed an online survey and knowledge examinations, both before and after attending a new tutorial, with answers from before and after the session being compared. RESULTS Pre-teaching satisfaction scores concerning teaching were low, at an average of 2.45 (out of 7), with a mean examination result of 6.53 (out of 10). Post-teaching average satisfaction increased by 3.20 points to 5.65 (out of 7) (p < 0.01) and examination scores increased by 1.53 points to 8.07 (out of 10) (p < 0.01). CONCLUSION Students are supportive of increased access to cadaver dissections of the ear, and facilitating this can improve satisfaction with otology teaching.

Abstract
OBJECTIVE To present a multifaceted approach to ophthalmology undergraduate medical education and to assess the efficacy of an eye dissection laboratory in enhancing medical student learning. DESIGN Curriculum review, validation, and student feedback evaluations. PARTICIPANTS Year 2 medical students enrolled in the University of Toronto's Doctor of Medicine Program. METHODS Student feedback evaluations were compiled from the University of Toronto undergraduate medical education student surveys before 2012-2016 and following introduction of the redesigned foundations ophthalmology curriculum at the University of Toronto (2017-2018). Students who participated in the Eye Dissection Lab as part of the newly designed curriculum completed the pre- and postsession satisfaction and overall interest in ophthalmology questionnaires and a knowledge-based test. RESULTS Analysis of 1640 student evaluations demonstrated an increase in ophthalmology curriculum rating following the launch of the foundations ophthalmology curriculum (p = 0.015). Among the 335 students who completed the eye dissection lab, there was a significant increase in the average scores for the satisfaction questionnaire, knowledge-based test, and level of interest in the field of ophthalmology from before and after the session, with improvements in scores noted in 91%, 42%, and 36% of the educational parameters of the participants, respectively (p < 0.001). CONCLUSIONS The newly designed foundations ophthalmology curriculum and the eye dissection lab at the University of Toronto serve as effective means for enhancing ophthalmology teaching in medical schools across Canada.

Abstract
Dissection is a unique multisensory educational experience and is essential to learning the anatomical construction of the human and animal bodies. This study aims to introduce a specialized design for the assessment of dissection and to discuss the assessment's attributes. The design was a product of the "assessment drives learning" concept and was developed to motivate students to dissect. Students were awarded "dissection points" based on prior group dissection and identification of structures. Students' perception of the design was examined, and content analysis was performed. The assessment consisted of two parts: the first assigning each student group structures to "pin" on their previously dissected cadavers; the second was a group peer evaluation. The most critical factor for the assessment's success was careful selection of structures assigned to students to pin. The assessment was fit for the purpose, valid, reliable, and had a significant educational impact. Eighty-three percent of students (n = 116) recommended maintaining the assessment design, as they felt it promoted a deep approach to learning as well as teamwork while reducing stress to a minimum. A strong correlation (Spearman's rho = 0.46, P < 0.0001) was present between the high rating of the design and the number of structures learned, as well as, high rating and lower stress level (Spearman's rho = 0.40, P < 0.0001). There was no apparent influence of grades on student perception of the effectiveness of the assessment. This specific design of evaluation could be used as part of anatomy education in veterinary and medical schools.

Abstract
It is universally recognized that cadaveric dissection is an essential part of anatomy training. However, it has been reported to induce mental distress in some students and impair their intrinsic motivation (IM) to study. One of the postulated reasons for this behavior is the lack of adequate information and preparation of students for cadaveric dissection. Therefore, it is hypothesized that providing relevant information prior to cadaveric dissection will ameliorate the mental distress, enhance the IM of students, and improve their academic performance. A cohort of occupational therapy students enrolled in an anatomy course were psychologically prepared for cadaveric dissection. Students were provided with a curated list of YouTube videos and peer-reviewed journal articles related to cadaveric dissection prior to the commencement of the anatomy course. All students were also required to attend an oral presentation immediately before commencing dissection. The control group included students who had not been provided with any resources in preparation for cadaveric dissection. Compared to the control group, students who had been prepared demonstrated better quality of cadaveric dissection, improved academic performance, reported less mental distress and greater IM. Moreover, students reported the oral presentation to be most relevant and journal articles to be least useful in their preparation. Therefore, this is an effective approach in the amelioration of mental distress and improvement of performance in anatomy students. Consequently, this study represents a paradigm shift in the pedagogy of anatomy, and could represent a vital element in the evolution of a revitalized anatomy curriculum.

Abstract
We utilized the physical manipulation of cadaveric donors by students to evaluate learning outcomes in two undergraduate anatomy courses. Students (n = 176) were assigned as those whom ‘manipulated’ (n = 100) or ‘did not manipulate’ (n = 76) donors, and data were compared to performance on laboratory assessments. A Fisher’s exact test was conducted within individual and combined course populations to assess if the relationship between physical touch and receiving a passing grade is more than expected by chance. BIO 201 ‘manipulating’ students received a ‘C’ or better (n = 58) vs. 6 D, F, or Withdraw grades (DFW) on lab practicals as compared to those who did not manipulate (n = 33 DFW vs. 18 C or better) (p < 0.0001). BIO 221 ‘manipulating’ students (n = 34) received a ‘C’ or better vs. DFW grades (n = 2), while ‘non-manipulating’ students were able to earn outcomes of ‘C’ or better (n = 13 vs. 12 DFW). However, students involved in donor manipulation were more likely to receive a ‘C or better’ (p = 0.0002). Analysis of the data as a single cohort indicates non-manipulating students are 7.24 times more likely to earn a ‘DFW’ on lab practicals, demonstrating that students are better prepared for laboratory assessments when encouraged to manipulate anatomical structures.

Abstract
Due to the Covid-19 pandemic, National Taiwan University anatomy teachers adopted asynchronous online video teaching and reduced the size of anatomy laboratory groups in April 2020. The aim of this study was to investigate the impact of these changes on medical students' learning. Before Covid-19, the performance of the 2019-2020 cohort was significantly better than that of the 2018-2019 cohort. However, the implementation of modified teaching strategies significantly lowered the laboratory midterm score of the 2019-2020 cohort in the second semester. Conversely, the final laboratory examination score of the 2019-2020 cohort was significantly higher than that of the 2018-2019 cohort. Through correlation analysis, lecture and laboratory examination scores were highly correlated. Additionally, the difference in lecture and laboratory z-scores between two cohorts, the Likert scale survey and free-text feedback of the 2019-2020 cohort, were conducted to show the impact of modified teaching strategies. There were several important findings in this study. First, the change in teaching strategies may temporarily negatively influence medical students to learn anatomy. Besides, analyzing the performance of laboratory assessments could be a complementary strategy to evaluate online assessments. Applying lecture examination scores to predict laboratory performance was a feasible way to identify students who may have difficulty in learning practical dissection. Finally, reducing group size together with reduced peer discussion may have a negative effect on learning cadaver dissection for students with low academic performance. These findings should be taken into consideration when anatomy teachers apply new teaching strategies in anatomy courses.

Abstract
Whole body dissection, once a long‐held method of learning and teaching in anatomy medical education, has largely been replaced by cost and time‐reduced methods of teaching. This paper reports on a longitudinal study of student knowledge acquisition and retention, following six annual intensive eight‐week elective anatomy by whole body dissection (AWBD) courses implemented between 2010 and 2015, utilizing a modified team‐based learning (TBL) pedagogy. A total of 160 students completed the intensive full‐time courses. During each course, students, in groups of five or six, completed the dissection of a whole cadaver. Students were assessed by a standardized practical test involving the accurate identification of 20 different tagged anatomical structures. All students (n = 160) completed pre‐course and end‐course individual assessments. Seventy students were assessed again 1 month after the course ended. A further 71 students were assessed 7 months later. A marked increase in topographical relational anatomical knowledge was demonstrated. The median pre‐course score was 9/20 (interquartile range 5). The median end‐course score was 19/20 (IQR 2), a statistically significant increase (p < 0.001). The assessments for the 70 students reassessed 1 month after the course ended showed no significant statistical change. The assessments for the further 71 students assessed 7 months later also showed no significant statistical change. The results of this study demonstrate that AWBD, provides significant acquisition and maintenance of three‐dimensional regional relational anatomical knowledge. As an elective, AWBD has a place in the medical curricula, particularly for students interested in a surgical or procedural based specialty career.

Abstract
The world has changed rapidly since the emergence of the COVID-19 pandemic, and the education community has not been immune to these changes. With abrupt school closings and a rapid transition to online teaching and learning, the educational technologies have been stretched to their limits and pedagogic approaches blossomed. As the world strives to reestablish normalcy, it will be under the influence of the long-lasting impact of the pandemic. This manuscript provides recommendations for the online conversion of anatomical sciences curricula in health sciences programs. Strategic guidelines are emerging for building on these changes to enhance teaching and learning in the current pandemic era.

Abstract
This study presents the design of a DL-framework to deliver anatomy teaching that provides a microfiche of the onsite anatomy learning experience during the mandated COVID-19 lockdown. First, using nominal-group technique, we identified the DL learning theories to be employed in blueprinting the DL-framework. Effectiveness of the designed DL-framework in anatomy teaching was demonstrated using the exemplar of the Head and Neck (H&N) course during COVID-19 lockdown, in the pre-clerkship curriculum at our medical school. The dissemination of the DL-framework in the anatomy course was informed by the Analyse, Design, Develop, Implement, and Evaluate (ADDIE) model. The efficiency of the DL-framework was evaluated using the first two levels of Kirkpatrick's model. Versatility of the DL-framework was demonstrated by aligning its precepts with individual domains of key learning outcomes framework. The framework's blueprint was designed amalgamating principles of: Garrison's community inquiry, Siemens' connectivism and Harasim's online-collaborative-learning; and improved using Anderson's DL-model. Following the implementation of the DL-framework in the H&N course informed by ADDIE, the framework's efficiency was evaluated. In total, 70% students responded to the survey assessing perception toward DL (Kirkpatrick's Level: 1). Descriptive analysis of the survey results showed that the DL-framework was positively received by students and attested that students had an enriched learning experience, which promoted collaborative-learning and student-autonomy. For, Kirkpatrick's Level: 2 i.e., cognitive development, we compared the summative assessment performance in the H&N course across three cohort of students. The results show that the scores of the cohort, which experienced the course entirely through DL modality was statistically higher (P < 0.01) than both the other cohorts, indicating that shift to DL did not have an adverse effect on students' learning. Using Bourdieu's Theory of Practice, we showed that the DL-framework is an efficient pedagogical approach, pertinent for medical schools to adopt; and is versatile as it attests to the key domains of students' learning outcomes in the different learning outcomes framework. To our knowledge this is the first-study of its kind where a rationale and theory-guided approach has been availed not only to blueprint a DL framework, but also to implement it in the MBBS curriculum.

ANATOMICAL SCIENCES EDUCATION 2021; 14:615-628. [PMID: 33460300 DOI: 10.1002/ase.2012] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Revised: 07/21/2020] [Accepted: 07/30/2020] [Indexed: 06/12/2023]
Abstract
The gross anatomy dissection course is considered to be one of the most important subjects in medical school. Advancing technology facilitates the production of e-learning material that can improve the learning of topographic anatomy during the course. The purpose of this study was to examine a locally produced audiovisual dissection manual's effects on performance in dissection, formal knowledge gained, motivation, emotions, learning behavior, and learning efficiency of the medical students. The results, combined with the total effort put into the production of the manual, should support decisions on further implementation of this kind of audiovisual e-learning resource into the university's curriculum. First-year medical students (n = 279) were randomly divided into three groups for two weeks within the regular dissection course hours during the dissection of the anterior and posterior triangles of the neck. Two groups received an audiovisual dissection manual (n = 96) or an improved written manual (n = 94) as an intervention, the control group (n = 89) received the standard dissection manual. After dissection, each student filled out tests and surveys and their dissections were evaluated. The audiovisual dissection manual did not have any significant positive effects on the examined parameters. The effects of the audiovisual dissection manual on the medical students' learning experience, as observed in this study, did not support further curriculum implementation of this kind of e-learning resource. This study can serve as an orientation for further evaluation and design of e-learning resources for the gross anatomy dissection course.

Abstract
PURPOSE Today, medical education emphasizes clinical applications of anatomic knowledge. In 2014, we instituted Clinically Applied Anatomy (CAA) within first-year Human Gross Anatomy at our university. The course was designed and overseen by academic plastic surgery. We hypothesized CAA would positively impact students' understanding, performance, and interest in human anatomy. METHODS From 2014 to 2018, 13 CAA case-based didactics were integrated into the anatomy curriculum without changing the total anatomy-related student hours; each emphasized the clinical relevance of overlooked (or memorized) anatomic detail. Clinically Applied Anatomy instructors led associated clinical cadaver dissections. Upon course completion, students from each participating class were anonymously surveyed. RESULTS One hundred sixty-four students completed the survey (75% response). Eighty-six percent reported CAA increased mastery of human anatomy, 77% stated CAA improved examination performance, 87% agreed CAA increased interest in anatomy itself, and 96% reported CAA increased their critical thinking of how understanding anatomy affects clinical care. Nearly half (49.4%) responded that CAA increased interest in applying for a procedurally oriented residency. When considering future integration of CAA into the medical school curriculum, 9% of students wanted less CAA, 61% wanted the same, and 30% wanted more. CONCLUSIONS Clinically Applied Anatomy significantly impacts medical students' anatomy education. Currently, 17 CAA faculty from 7 departments/divisions participate in all 26 of our school's anatomy sessions. As per our institution, we advocate this cost-effective and impactful initiative be led by academic plastic surgeons. These clinicians possess broad and specialized anatomic expertise as well as the leadership and interdisciplinary working relationships needed to enroll a multidisciplinary team of clinical educators.

Abstract
Anatomy education continues to evolve in health professional programs as curricula shift to competency-based models and contact hours decrease. These changes in curricula may significantly alter the learning environment for students. Importantly, changes in learning environment have been shown to impact student learning strategies and well-being. It follows, then, that an investigation of students' perceptions of the learning environment is key to understand the impact of modern anatomy curriculum alterations. The current pilot study evaluated the impact of modifying examination format on the learning environment of physical therapy students participating in a human cadaveric anatomy course. Two study cohorts of first year (entry-level) physical therapy students were invited to complete a preliminary learning environment questionnaire with 13 visual analog scale items and four short answer items. One study cohort was tested with a viva (oral) practical examination, and the other, with a bell-ringer practical examination. Analysis of quantitative items revealed two significant findings: physical therapy students in the bell-ringer cohort found it was more difficult to prepare for their examination, and that they had inadequate time to respond to questions compared to the viva cohort. Analysis of qualitative items revealed distinct themes that concerned physical therapy student learning environment specific to cadaveric anatomy. These results demonstrate that examination format can influence the learning environment of physical therapy students studying cadaveric anatomy. As a result, care needs to be taken to ensure that modernized curricula align the examination format to the method of instruction and the future application of students' knowledge in clinical practice.

Abstract
This manuscript summarizes presentations of a symposium on key considerations in design of biomechanical models at the 2019 Basic Science Focus Forum of the Orthopaedic Trauma Association. The first section outlines the most important characteristics of a high-quality biomechanical study. The second section considers choices associated with designing experiments using finite element modeling versus synthetic bones versus human specimens. The third section discusses appropriate selection of experimental protocols and finite element analyses. The fourth section considers the pros and cons of use of biomechanical research for implant design. Finally, the fifth section examines how results from biomechanical studies can be used when clinical evidence is lacking or contradictory. When taken together, these presentations emphasize the critical importance of biomechanical research and the need to carefully consider and optimize models when designing a biomechanical study.

Abstract
PURPOSE This study aimed to compare the students' scores of the spot (spotter/classical/traditional/tag/ring/bell-ringer) test (3D environment) performed in the laboratory with the slide test (gross anatomy images) (2D environment) in the class. The observation of our department regarding both types for practical examination was reported, in terms of exam marks of the students. Both are preferred as the practical examination types for gross anatomy course our in medical faculty. METHODS The 29 blocks' scores in 5 years (2013/2014-2017/2018) belonging to first- and second-year medical students' spot tests and slide tests are evaluated retrospectively and statistically compared. Correlations of the spot tests and the slide tests, besides the correlations between theoretical examinations and the practical examination types, are calculated. RESULTS Spot test scores were significantly higher (p < 0.05) in nine blocks, while slide test scores were higher significantly (p < 0.05) in fourteen. There was no statistically significant difference between the practical examination types (spot/slide) in six blocks. There were correlations between the spot test and the slide test in all blocks (p < 0.001). CONCLUSION It is considered that the spot test reflects the success/ability in a 3D environment, while the slide test reflects it in the 2D environment. In conclusion, neither of these two types of examinations stands out absolutely. Both types of examinations have their own features in areas, such as assessment power, applicability, and effect on success.

Abstract
BACKGROUND Anatomy education has long been considered fundamental to the medical profession. Recently, Australasian medical schools have favored prosected human material, models and medical imaging in their anatomy curriculum with only 3 medical schools offering whole-body dissection. The aim of this study was to explore the knowledge acquisition and perceptions of an elective anatomy by whole body dissection (AWBD) course for senior medical students. METHODS In the 2017 AWBD course, 53 self-selected senior medical students carried out dissections over an 8-week period. Students were assessed via true/false questions and practical tests involving the identification of structures on anatomical images at precourse, mid-course and end-course. In addition, at completion of the course, students completed a questionnaire using a 5-point Likert scale and 2 open-ended questions. Quantitative data analysis was conducted on test scores and questionnaire data using a paired-sample t-test and descriptive statistics. Qualitative data were coded and categorised into themes. RESULTS There was a significant improvement (p < 0.0001) in student test scores from pre-course (mean 34.1 ± 12.9%) to mid-course (mean 74.8 ± 9.4%) and end-course (mean 75.4 ± 9.8%). Analysis of the questionnaire data showed strongly favorable perceptions of the course, highlighting dissection, complemented by Structure, Clinical, Objective-Referenced, Problem-Based, Integrated and Organized (SCORPIO) teaching, frequent testing and senior surgeon supervision as beneficial teaching methods. CONCLUSIONS Dissecting in small groups has been shown to be an effective part of anatomy learning. Our study suggests complementary teaching methods as possible augmenters to a well-structed, small group AWBD course. We have presented a framework suitable for an intensive AWBD course within medical curricula, that was valued by participants, and improved students' knowledge of anatomy.

Abstract
As medical education advances, cadaveric dissection is no longer the sole modality to teach anatomy. In light of this, there is limited data regarding how incoming medical students perceive the importance of cadaveric dissection and whether they continue to desire the experience as they consider matriculating to medical school. Surveys were sent to incoming first-year medical students concerning their views of death and dissection. Our data show a strong and temporally reproducible opinion that cadaveric dissection is important among incoming medical students. This survey also reviews the predominant emotional reactions generated in anticipation of the cadaveric dissection experience.

Abstract
The goal of this observational study was to develop effective approaches to introduce first year medical students to gross anatomy/embryology in a compressed time frame. Pedagogical reorganization of anatomy instruction in the regions of Lower Extremity and Head and Neck was based upon core clinical conditions taught in second-year and USMLE Step 1 board review courses. These conditions were not presented as clinical problems, as many students had limited prior training in medical terminology, but focused upon clinical symptoms, allowing for direct correlation of structure and function. Instruction stressed vocabulary acquisition and was extended to prepare for laboratory dissections. Overall methodology was multimodal, including "flipped" and traditional lectures, study of prosections/radiographs and small group laboratory review sessions. Content was significantly reduced: knowledge of muscle actions and innervations was required, not muscle origins and insertions. Performance was evaluated by criterion-based written examinations that included a set of questions (34) asked repetitively over an 8 year period (n = 606 students) and by regional practical exams. Mean scores in all areas were sustained or numerically improved, despite the compression of instruction duration. Analysis showed no significant differences based upon question format or instructional modality. Despite the high performance levels, students needing assistance in learning could be identified by score distributions. A survey of students indicated that these changes effectively decreased stress and facilitated review for the USMLE Step 1 Board examination. These results suggest that training in gross anatomy can be modified to a compressed duration by instruction in the context of clinical symptomatology.

Abstract
INTRODUCTION For students studying anatomy, dissection of the human body can elicit a wide range of intellectual and emotional responses that are subject to change over the duration of a course. The purpose of this study was to determine how overall emotional responses change over time, if there are differences in responses by gender and previous laboratory exposure, and if these responses impact course performance. METHODS First-year medical students enrolled in the Human Structure and Function course at the University of Vermont, and in the Organ Systems 1, 2, and 3 courses at Morehouse School of Medicine were given a series of four surveys across the first-year curriculum. Data were gathered regarding age, gender, and previous laboratory exposure. Students were asked to rate their level of 15 positive and negative emotions, and their desire to avoid or approach the laboratory and donors. These responses were translated to three measures: (a) a positive response index (PRI), (b) a negative response index (NRI), and (c) an avoid-approach index (AAI). Responses were followed longitudinally and matched with anatomy practical examination grades. RESULTS Gender and previous laboratory exposure status were both significantly related to emotional responses at different points throughout the year, and unique patterns of responses across the year emerged within each group. Higher PRI and AAI were positively correlated with some practical examination scores. CONCLUSIONS Data suggest that gender and previous laboratory exposure status influence emotional responses to dissection, and that these responses may have an effect on course performance.

Impact of Background Music on Medical Student Anxiety and Performance During Anatomical Dissections: A Cluster Randomized Interventional Trial. ANATOMICAL SCIENCES EDUCATION 2020; 13:427-435.

Abstract
Anatomical dissection on cadavers can be a source of anxiety for medical students. Studies in other stressful settings have shown a reduction in anxiety when there is background music. The objective of this study was to determine if music can have an impact on student anxiety, student satisfaction, and student performance in dissection room. This cluster randomized interventional trial included 187 second-year medical students. The intervention was standardized background music, selected based on the literature, with a tempo of between 60 and 80 bpm. Six balanced clusters were randomized (1:1) to music or no music during dissection sessions. The main assessment criterion was a validated self-evaluation scale score for anxiety, the State Trait Anxiety Inventory. Student satisfaction was measured using a visual analog scale and dissection performance was evaluated by an examination. The outcomes were analyzed with mixed models adjusted on group effect, chronic anxiety, and confounding factors. A significant (58%) relative decrease in acute anxiety, odds ratio 0.423 [0.160; 0.710] was found for the music intervention group. Music also had a positive impact on performance with students in the intervention group attaining higher grades than those in the control group (0.42/10 higher, P = 0.0016). The study also showed a nonsignificant increase in satisfaction with 0.37 extra points (P = 0.137) in the intervention group. Background music had a significant impact on anxiety in the dissection room and on technical and theoretical performance in the subsequent anatomy examination. This music intervention could be extended to other stressful work environments.

Abstract
Few discussions regarding instructional methods incite as much passion as the debate over dissection versus prosection. Despite numerous analyses, few studies have isolated the impact of dissection versus prosection from the numerous variables that are involved in anatomy education. This study used a retrospective design to assess the effect of peer teaching with dissection or prosection on anatomical knowledge retention of the peer teachers. Exam scores were analyzed from three cohorts of students (N = 184) who were enrolled in a Musculoskeletal System course in an allopathic medical school between academic years 2014-2017. Students in the first 2 yr learned anatomy of an assigned region through traditional dissection, whereas students in the third year learned anatomy of the same regions on prosected specimens. The effect of these instructional methods on anatomical knowledge retention was measured by student performance on a teaching-readiness quiz, written exam, and practical examination. One advantage of this study is the stability of variables between cohorts. Student groups peer taught the same objectives; course sequencing and content remained consistent between years; students spent the same amount of time learning their material, regardless of learning modality (dissection or prosection); and students were tested in the same manner. Comparisons of student performance data suggest that anatomy knowledge was equivalent, regardless of the instructional method (dissection or prosected cadavers) but is strongly associated with prior anatomy experience. Findings from this study support previous studies that conclude that there are no disparities in the effectiveness of learning anatomy via dissection or prosection.

Abstract
The role of human dissection in modern medical curricula has been a topic of intense debate. In part, this is because dissection can be time-consuming and curricular hours are being monitored more carefully. This has led some to question the efficacy and importance of dissection as a teaching method. While this topic has received considerable attention in the literature, the question of how dissection impacts learning has been difficult to evaluate in a real-world, high-stakes setting since participation in dissection is often one of many variables. In this study, this challenge was overcome due to a change in the curriculum of a Special Master Program (SMP) that permitted a comparison between two years of students that learned anatomy using prosection only and two years of students that participated in dissection laboratories. Since each class of SMP students took courses in the medical school, and the medical school anatomy curriculum was constant, medical student performance served as a control throughout the study period. Results demonstrate that SMP students who learned through prosection had lower performance on anatomy practical and written examinations compared to medical students. When the SMP program changed and students started participating in dissection, there were measurable improvements in both practical and written examinations. These findings provide evidence of dissection's role in learning and applying anatomy knowledge both within and outside the gross anatomy laboratory.

Abstract
Using cadaveric instruction in a graduate-level anatomy course is an expensive and time-consuming undertaking. While this is a worthwhile endeavor, most first-year medical students and students in the health fields struggle with the independent, self-directed learning approach in the cadaveric laboratory, and going beyond rote memorization of the material. As such, effective assessment tools that maximize student learning in the cadaveric laboratory are critical, especially if no lecture component is present. Dissection quality often reflects student attention to detail and therefore may be tied to overall performance in the course. The aim of this study was to investigate the relationship between weekly table quizzes and the overall student outcomes in a graduate biomedical human dissection class as well as examining the benefits and implications of this approach. In this course, a uniquely structured weekly quiz assessed dissection quality and probed student understanding in human anatomy. Student data compiled from 5 years of dissection courses were analyzed to evaluate the relationship between performance in the weekly assessment and on the unit examinations. The results showed a statistically significant relationship between the weekly quizzes and the student examinations at the end of each dissection block in 2013, 2015, 2016, and 2017. The data suggest a potential correlation between performance on weekly quizzes and on unit examinations. The unique nature of the table quizzes provides the students with the opportunity to practice the retrieval of their knowledge, feel more guided throughout their dissection, and receive immediate feedback on their performance. This assessment tool also provides a way to predict student outcomes and an opportunity for early intervention to help at-risk students. The analysis of this research study contributes to the need for more data on the usage of assessment tools in a graduate human dissection class.

Abstract
The most effective method to teach gross anatomy is largely unknown. This study examined two teaching methods utilized in a physical therapy and occupational therapy gross anatomy course, (1) alternating dissection with peer teaching every other laboratory session and (2) faculty demonstrations during laboratory sessions. Student (n = 57) subgroup (A or B) academic performance was determined using written, laboratory practical, and palpation practical examinations. Subgroup A performed significantly better on laboratory practical examination questions pertaining to dissected, in comparison to peer-taught structures (67.1% vs. 60.2%, P = 0.008). Subgroup B performed significantly better on laboratory practical examination questions pertaining to peer-taught, in comparison to dissected structures (64.1% vs. 57.9%, P = 0.001). When Subgroup A was compared to Subgroup B, there were no statistically significant differences on laboratory practical examination question types, whether the subgroup learned the structure through dissection or peer teaching. Based on within and between subgroup comparisons, faculty demonstrations had no effect on written, laboratory practical, or palpation practical examination scores. Although limited, data suggest that the student roles when alternating dissection with peer teaching every other laboratory session appear to be equally effective for learning gross anatomy. The benefits of this method include decreased student/faculty ratio in laboratory sessions and increased time for independent study. Faculty demonstrations during laboratory sessions do not seem to improve student academic performance.

Abstract
PURPOSE Perfusion techniques on cadavers are heterogeneous and imperfect. The objective of this study was to improve the existing circulation model for surgical simulation on cadavers. METHODS We used a three-step experimental approach. The first part of the experiment tested two variables: the type of circuit and the use of a heater for perfusion. The second approach evaluated two parameters: the injection fluid and the type of body conditioning (embalmed or freshly dead prepared using different washing techniques). The third one was an improvement on the best circulation obtained, which focused on the injection fluid. To compare the realism of these different techniques, we constructed a score with realism parameters: the volume of return flow, the presence of peripheral venous return and the perfusion of abdominal arteries. RESULTS We found that the use of a heater seemed to improve the perfusion, while performing an arteriovenous bypass did not seem very effective. A correlation rate of 0.84 was found between the realism score and the injected fluid chosen. The best score (4/6) was found for a non-embalmed body with a low-pressure washing technique using a gelatin-based liquid at a concentration of 4 g/L for circulation. Scores obtained using embalmed bodies for both injection fluids for high-pressure washing or for 8-g/L gelatin injection fluid did not exceed 3/6. CONCLUSIONS We showed that using a non-embalmed body with low-pressure washing and a 4-g/L gelatin-based fluid was the most effective technique for cadaver perfusion.

Abstract
Detailed knowledge of anatomy is an essential part of surgical practice. However, there are many drawbacks in anatomy education that make many residents feel inadequate when they start performing surgeries. Cadaveric dissection courses aim to close the gap between the anatomic knowledge and surgical practice. This review focuses on the role of cadaveric dissection on surgical education, and additionally states the panel decision of the Surgical Anatomy and Technologies Association on the proper use of cadavers.

Abstract
PURPOSE Dissection provides direct experience in anatomy, which constitutes an essential discipline for medical students. For this purpose, we created a dissection guide for students in the 2nd-year of medical studies at the Grenoble University School of Medicine. The objective was to evaluate this tool of reverse pedagogy in terms of student satisfaction and educational interest. METHODS Every 2nd-year student takes four sessions of limb dissection. To assist this dissection course, we developed a photographic guide launched in 2013. It includes an introduction presenting a methodology for dissection, followed by detailed protocols for each dissection area. Each step is illustrated with captioned photographs associated with a concise explanatory text. A questionnaire was then sent to 242 students to assess the impact of this tool and their overall satisfaction. RESULTS Overall student satisfaction with this guidebook was rated 8.1 out of 10 with a 93.2% with significant improvement (p = 0.0137) and 78.7% of them declaring they had a better understanding of anatomy and mastery of the dissection techniques, respectively. In addition, students assessed the usefulness of the dissection guide at 3.6 out of 4 with the relevance of the content and presentation judged at 3.4 out of 4. Finally, the exam scores increased significantly with use of the guidebook (p < 0.0001). CONCLUSIONS Students deemed the organization of this anatomy tutorial as highly satisfactory, and using the guidebook as a reference in dissection sessions allowed students to prepare for the dissection and improve their knowledge of anatomy, as demonstrated by improved exam scores.

Abstract
To improve student preparedness for anatomy laboratory dissection, the dental gross anatomy laboratory was transformed using flipped classroom pedagogy. Instead of spending class time explaining the procedures and anatomical structures for each laboratory, students were provided online materials to prepare for laboratory on their own. Eliminating in-class preparation provided the opportunity to end each period with integrative group activities that connected laboratory and lecture material and explored clinical correlations. Materials provided for prelaboratory preparation included: custom-made, three-dimensional (3D) anatomy videos, abbreviated dissection instructions, key atlas figures, and dissection videos. Data from three years of the course (n = 241 students) allowed for analysis of students' preferences for these materials and detailed tracking of usage of 3D anatomy videos. Students reported spending an average of 27:22 (±17:56) minutes preparing for laboratory, similar to the 30 minutes previously allocated for in-class dissection preparation. The 3D anatomy videos and key atlas figures were rated the most helpful resources. Scores on laboratory examinations were compared for the three years before the curriculum change (2011-2013; n = 242) and three years after (2014-2016; n = 241). There was no change in average grades on the first and second laboratory examinations. However, on the final semi-cumulative laboratory examination, scores were significantly higher in the post-flip classes (P = 0.04). These results demonstrate an effective model for applying flipped classroom pedagogy to the gross anatomy laboratory and illustrate a meaningful role for 3D anatomy visualizations in a dissection-based course.

Abstract
The purpose of this study was to evaluate the extracurricular cadaveric dissection program available to medical students at an institution with a modern (time-compressed, student-centered, and prosection-based) approach to medical anatomy education. Quantitative (Likert-style questions) and qualitative data (thematic analysis of open-ended commentary) were collated from a survey of three medical student cohorts who had completed preclerkship. Perceived benefits of dissection included the hands-on learning style and the development of anatomy expertise, while the main barrier that limited participation was the time-intensive nature of dissection. Despite perceived benefits, students preferred that dissection remain optional. Analysis of assessments for the MD2016 cohort revealed that dissection participation was associated with enhanced performance on anatomy items in each systems-based unit examination, with the largest benefits observed on discriminating items that assessed knowledge application. In conclusion, this study revealed that there are academic and perceived benefits of extracurricular participation in dissection. While millennial medical students recognized these benefits, these students also indicated strong preference for having flexibility and choice in their anatomy education, including the choice to participate in cadaveric dissection.

Abstract
INTRODUCTION Good clinical knowledge of anatomy, taught in medical school, is necessary for practicing physicians. It is a key feature of performance on the United States Medical Licensing Examination Step 1 score. Student performance on anatomy is also an early indicator of overall medical student performance. Unfortunately, curricular time provided for the teaching of anatomy has declined significantly over the last 30 years, leading to growing concerns that the anatomical knowledge of new medical graduates may not be adequate. Data regarding the impact of these changes to the medical school curriculum are lacking, with studies often being limited in number of medical students or time. METHODS This study examined the anatomy knowledge of students on third-year clinical rotations at Tulane University Medical School. Oral examinations were administered at the conclusion of the junior surgical clerkship. Data on performance were collected over a 5-year period from 690 medical students tested in their knowledge of anatomy, and the other basic sciences collectively considered as pathophysiology. RESULTS Over the 5-year period, student total scores by year increased in all categories tested. However, during the course of the students' third-year clerkships, the later in the year the students rotated on surgery, the more their scores progressively declined. Unfortunately, this fall was most severe in the knowledge of anatomy. DISCUSSION Although it is possible to teach anatomy in increasingly shorter periods of time, such that the students achieve high test scores in the standardized short answer examinations, it is clear that their knowledge, as applied to clinical care, rapidly declines the further they get away from Step 1 studying. Further study is necessary to elucidate the weaknesses in the current basic science curricula as they pertain to anatomy and to devise mechanisms to assure retention of this critical science during clinical rotations and beyond into practice.

Abstract
Medical schools in the United States continue to undergo curricular change, reorganization, and reformation as more schools transition to an integrated curriculum. Anatomy educators must find novel approaches to teach in a way that will bridge multiple disciplines. The cadaveric extraction of the central nervous system (CNS) provides an opportunity to bridge gross anatomy, neuroanatomy, and clinical neurology. In this dissection, the brain, brainstem, spinal cord, cauda equina, optic nerve/tract, and eyes are removed in one piece so that the entire CNS and its gateway to the periphery through the spinal roots can be appreciated. However, this dissection is rarely, if ever, performed likely due to time constraints, perceived difficulty, and lack of instructions. The goals of this project were (i) to provide a comprehensive, step-by-step guide for an en bloc CNS extraction and (ii) to determine effective strategies to implement this dissection/prosection within modern curricula. Optimal dissection methods were determined after comparison of various approaches/tools, which reduced dissection time from approximately 10 to 4 hours. The CNS prosections were piloted in small group sessions with two types of learners in two different settings: graduate students studied wet CNS prosections within the dissection laboratory and medical students used plastinated CNS prosections to review clinical neuroanatomy and solve lesion localization cases during their neurology clerkship. In both cases, the CNS was highly rated as a teaching tool and 98% recommended it for future students. Notably, 90% of medical students surveyed suggested that the CNS prosection be introduced prior to clinical rotations. Anat Sci Educ 11: 185-195. © 2017 American Association of Anatomists.

Abstract
Cadaver dissection (CD) is considered a tool for studying the structural details of the human body. Lately, conflicting opinions regarding the utility of this modality in medical training have been published in medical literature. This review of the literature examines the status of anatomy teaching with CD in traditional, modern, and postgraduate medical training across the world. Literature published in the En-glish language on topics related to CD in the past 3 decades was scrutinized using different search engines. About 200 full texts were reviewed. We describe how medical schools have continued to include CD in anatomy teaching in the traditional or modified form. Medical schools that stopped or decreased CD have learnt from their experiences, and have restarted it in modified forms by integrating it vertically with medical training. In addition, CD activities have increased in postgraduate anatomy courses, surgery training, and voluntary/optional CD programs. CD, when integrated vertically, still has a part to play in medical training in modified ways. This overview may help curriculum designers to place CD in medical curricula and training programs in a justified manner.

Abstract
Profound anatomical knowledge is the basis for modern demands in medicine and surgery, but many countries worldwide including Australia and New Zealand have discontinued offering dissection courses to medical and dental students during the past decades. This educational project done in Australia aimed at enhancing basic and advanced anatomy teaching by engaging a sub-group of second-year undergraduate students of a compulsory prosection- and model-based anatomy course (n = 54/170) in an optional multimodal course, which should easily articulate with a vertical curriculum. With topographical cadaver dissections as core, peer student-teams prepared and peer-assessed anatomy lectures based on clinical topics, which were rated highly by the peers and teachers. Anatomical knowledge was tested by quizzes and a multiple-choice examination. Individual dissection skills were self- and teacher-assessed. A final course grade was assigned based on these assessments. The grades in the system-based compulsory course achieved by the attendees of the paralleling dissection course were compared with their peers attending other optional courses. After beginning of the semester, the students in the dissection course performed similar, significantly (P < 0.005) improved during the semester (78.5% vs. 69.9%, 70.1% vs. 64.1%), but in the integrated (including anatomy, biochemistry, physiology) final examination at the end of the year only tended to higher scores. As assessed through interviews and a voluntary questionnaire, all students of the optional dissection course liked these activities, which enhanced their learning experience. Thus, this concept elegantly integrates anatomical dissection with modern teaching demands and is feasible for implementation in modernized curricula.

Abstract
Anatomy students are typically provided with two-dimensional (2D) sections and images when studying cerebral ventricular anatomy and students find this challenging. Because the ventricles are negative spaces located deep within the brain, the only way to understand their anatomy is by appreciating their boundaries formed by related structures. Looking at a 2D representation of these spaces, in any of the cardinal planes, will not enable visualisation of all of the structures that form the boundaries of the ventricles. Thus, using 2D sections alone requires students to compute their own mental image of the 3D ventricular spaces. The aim of this study was to develop a reproducible method for dissecting the human brain to create an educational resource to enhance student understanding of the intricate relationships between the ventricles and periventricular structures. To achieve this, we created a video resource that features a step-by-step guide using a fiber dissection method to reveal the lateral and third ventricles together with the closely related limbic system and basal ganglia structures. One of the advantages of this method is that it enables delineation of the white matter tracts that are difficult to distinguish using other dissection techniques. This video is accompanied by a written protocol that provides a systematic description of the process to aid in the reproduction of the brain dissection. This package offers a valuable anatomy teaching resource for educators and students alike. By following these instructions educators can create teaching resources and students can be guided to produce their own brain dissection as a hands-on practical activity. We recommend that this video guide be incorporated into neuroanatomy teaching to enhance student understanding of the morphology and clinical relevance of the ventricles.

Abstract
Lincoln Memorial University-DeBusk College of Osteopathic Medicine (LMU-DCOM) offers an optional three-week summer Anatomy Boot Camp course (ABC) to facilitate students' transition into medical school and promote retention of anatomy subject matter. The pre-matriculation program is a supplemental instruction course that utilizes a small group learning format. Boot camp instruction is led by teaching assistants and two anatomy professors. Enrollees gain early exposure to Medical Gross Anatomy (MGA) course subject matter, which is taught in the fall semester, and learn study skills necessary to excel in medical school. No grade is assigned for the course, therefore participants can study without the fear of potentially affecting grades. This study evaluates the effectiveness of the LMU-DCOM ABC course using data from four consecutive summers. Independent two-sample t-tests were used to compare ABC to non-ABC students for the following variables: incoming grade point average (GPA) and Medical College Admission Test® (MCAT®) scores, MGA written and laboratory practical examination grades, and final MGA course grade. Additionally, a 26-question survey was administered to 2012-2014 boot camp participants. There were no significant differences in incoming GPA and MCAT scores. However, boot campers scored significantly higher on the first two lecture and laboratory examinations (P < 0.05) for each year of the study. Thereafter scores varied less, suggesting a faster head start for boot camp participants. Mean MGA final grade was on average 3% higher for the boot camp cohort. The survey feedback supports that the ABC course assists with the academic and social transition into medical school. Anat Sci Educ 10: 215-223. © 2016 American Association of Anatomists.

Abstract
Currently, the importance of human anatomical dissection have come under debate in many countries but there are not references in Venezuela on this concern. This survey's aim is to assess the insights of Venezuelan surgeons and their outlines of usage of human anatomical dissection in teaching and learning human anatomy. Sixty-five Venezuelan surgeons at the Centro Médico Docente La Trinidad completed an anonymous survey on current and future teaching practices in human anatomy. Eighty-nine point two three percent of surveyed (n=58) conferred importance to human anatomical dissection despite the arrival of new innovations in learning human anatomy. The group surveyed view human anatomical dissection-based teaching as the most beneficial method of teaching human anatomy and it should be bolstered in human anatomical education with matching use of three-dimensional computerized tomography imaging as a complementary form for teaching and learning.

Abstract
Utilizing reality anatomy such as dissection and demonstrating using cadavers has been described as a superior way to create meaning. The chemicals used to embalm cadavers differentially alter the tissue of the human body, which has led to the usage of different processes along the hard to soft-fixed spectrum of preserved cadavers. A questionnaire based approach was used to gain a better insight into the opinion of anatomists on the use of preserved cadavers for the teaching of human anatomy. This study focused on anatomy teachers in the United Kingdom and Ireland. From the 125 participating anatomists, 34.4% were medically qualified, 30.4% had a PhD in a non-anatomical science and 22.4% had a PhD in an anatomical science, these figures include ten anatomists who had combinations of MD with the two other PhD qualifications. The main findings from the questionnaire were that 61.6% of participants agreed that hard-fixed formalin cadavers accurately resemble features of a human body whereas 21.6% disagreed. Moreover, anatomists rated the teaching aids on how accurately they resemble features of the human body as follows: plastic models the least accurate followed by plastinated specimens, hard fixed cadavers; soft preserved cadavers were considered to be the most accurate when it comes to resembling features of the human body. Though anatomists considered soft preserved cadavers as the most accurate tool, further research is required in order to investigate which techniques or methods provide better teaching tool for a range of anatomical teaching levels and for surgical training.

Abstract
The purpose of this study was to design a one-hour brain dissection protocol for a medical neuroscience course and evaluate the short and long-term effects of its implementation on medical students. First-year medical students (n = 166) participated in a brain dissection activity that included dissection of the basal nuclei and associated deep brain structures. Short-term retention was assessed by administering identical pre- and post-activity tests involving identification of brain structures. Following the brain dissection, the students' posttest scores were significantly higher (68.8% ± 17.8%; mean percent score ± SD) than their pretest scores (35.8% ± 20.0%) (P ≤ 0.0001). Long-term retention was evaluated by conducting an identical assessment five months after completion of the course. Students who participated in the dissection activity (n = 80) had significantly higher scores (46.6% ± 23.8%) than the students who did not participate in the dissection activity (n = 85) (38.1% ± 23.9%) (P ≤ 0.05). In addition to the long-term retention assessment, the NBME® Subject Examination scores of students who participated in the dissection activity were significantly higher than the students who did not participate in the dissection activity (P ≤ 0.01). Results suggest that this succinct brain dissection activity may be a practical addition to an undergraduate medical neuroscience course for increasing the effectiveness of neuroanatomy training. This effect may have long-term benefits on knowledge retention and may be correlated with higher performance levels on standardized subject examinations.
