Coming changes in veterinary anatomy: what is or should be expected?

Veterinary Students and Faculty Partner in Developing a Virtual Three-Dimensional (3D) Interactive Touch Screen Canine Anatomy Table

As educational technology advances, it is imperative that universities responsibly and appropriately adapt new approaches to enhance teaching and learning. Over a 6-month period, veterinary students at Ross University School of Veterinary Medicine (RUSVM) spearheaded the improvement of a proprietary prototype virtual interactive three-dimensional (3D), touch screen, canine anatomy table (APEX). Eight veterinary students with a grade of 80% or higher in their anatomy courses were hired as research assistants to identify and characterize 306 virtual anatomical structures. Descriptive statistics were used to assess students' (1) accuracy in reviewing assigned anatomical structures, and (2) perceptions surrounding the use of APEX as an educational anatomical tool. The overall accuracy rating was 3.73 on a 4-point scale, and students reported their experience as enjoyable (median 4 on a 5-point Likert scale) and beneficial to their knowledge of veterinary anatomy (median 4). In addition, 29 RUSVM faculty were surveyed on both the prototype APEX table as well as the student-improved version. Faculty agreement with utilization of APEX in RUSVM curriculum increased from Likert mean = 2.0 to a mean of 3.9 (p = < 0.001) between the two versions. Study results support the use of veterinary students to critically assess the development of anatomical educational tools for veterinary anatomy. Furthermore, students and faculty supported acceptance of technology in teaching and learning veterinary anatomy, and reported enjoyment and benefit of its use.

Student Perceptions of Veterinary Anatomy Practical Classes: A Longitudinal Study

Using cadaveric material to teach veterinary students poses many challenges. However, little research exists on the contribution of this traditional approach to student learning. This longitudinal study aimed to investigate student perceptions of cadaver-based anatomy classes in a vertically integrated veterinary curriculum at the University of Nottingham's School of Veterinary Medicine and Science. Likert-scale statements and free-text boxes were used in a questionnaire distributed to second-year veterinary students (response rate 59%, 61/103). The same questionnaire was subsequently distributed to the same cohort 2 years later, in the students' fourth year of study (response rate 68%, 67/98). Students agreed that cadaver-based activities aid their learning, and they particularly value opportunities to develop practical skills while learning anatomy. There are few changes in perception as undergraduates progress to clinical years of teaching. Students perceive anatomy to be important, and feel that their learning has prepared them for clinical placements. This study emphasizes the importance of using cadaveric materials effectively in anatomy teaching and, in particular, using clinical skills training to enhance the anatomy curriculum.

"Let's get physical": advantages of a physical model over 3D computer models and textbooks in learning imaging anatomy

Three-dimensional (3D) information plays an important part in medical and veterinary education. Appreciating complex 3D spatial relationships requires a strong foundational understanding of anatomy and mental 3D visualization skills. Novel learning resources have been introduced to anatomy training to achieve this. Objective evaluation of their comparative efficacies remains scarce in the literature. This study developed and evaluated the use of a physical model in demonstrating the complex spatial relationships of the equine foot. It was hypothesized that the newly developed physical model would be more effective for students to learn magnetic resonance imaging (MRI) anatomy of the foot than textbooks or computer-based 3D models. Third year veterinary medicine students were randomly assigned to one of three teaching aid groups (physical model; textbooks; 3D computer model). The comparative efficacies of the three teaching aids were assessed through students' abilities to identify anatomical structures on MR images. Overall mean MRI assessment scores were significantly higher in students utilizing the physical model (86.39%) compared with students using textbooks (62.61%) and the 3D computer model (63.68%) (P < 0.001), with no significant difference between the textbook and 3D computer model groups (P = 0.685). Student feedback was also more positive in the physical model group compared with both the textbook and 3D computer model groups. Our results suggest that physical models may hold a significant advantage over alternative learning resources in enhancing visuospatial and 3D understanding of complex anatomical architecture, and that 3D computer models have significant limitations with regards to 3D learning.

Teaching bovine abdominal anatomy: use of a haptic simulator

Traditional methods of teaching anatomy to undergraduate medical and veterinary students are being challenged and need to adapt to modern concerns and requirements. There is a move away from the use of cadavers to new technologies as a way of complementing the traditional approaches and addressing resource and ethical problems. Haptic (touch) technology, which allows the student to feel a 3D computer-generated virtual environment, provides a novel way to address some of these challenges. To evaluate the practicalities and usefulness of a haptic simulator, first year veterinary students at the Royal Veterinary College, University of London, were taught basic bovine abdominal anatomy using a rectal palpation simulator: "The Haptic Cow." Over two days, 186 students were taught in small groups and 184 provided feedback via a questionnaire. The results were positive; the majority of students considered that the simulator had been useful for appreciating both the feel and location of key internal anatomical structures, had helped with their understanding of bovine abdominal anatomy and 3D visualization, and the tutorial had been enjoyable. The students were mostly in favor of the small group tutorial format, but some requested more time on the simulator. The findings indicate that the haptic simulator is an engaging way of teaching bovine abdominal anatomy to a large number of students in an efficient manner without using cadavers, thereby addressing some of the current challenges in anatomy teaching.
