It is often argued that anatomy can only be effectively taught through individual student dissection. Such an approach requires an enormous number of cadavers, which puts a strain on any source, even those that are morally defensible. There is no evidence, however, that this approach is educationally necessary, as shown in published studies (some below). If you are aware of other examples you believe to be important to include here, please send the information to HEVM for consideration.

This is an interactive program of two-dimensional images of the dissection of a dog. It was produced by Dr. Ray Whalen at the Colorado State University, College of Veterinary Medicine and Biomedical Sciences. Although it is meant to be used in conjunction with traditional dissection, it could be used to enhance a student’s learning through prosections. Part of it is evaluated in Linton et al, 2005.

Adams, D.R. 1974 “The teaching of comparative gross anatomy through the prosection approach” Journal of Veterinary Medical Education 1(1):16-17
As there was insufficient time to dissect much more than the thoracic and pelvic limbs, it was decided to use prosections combined with freshly killed material and live animals, totally discontinuing the dissection of embalmed material.

Alexander, Justin. 1970 Dissection versus prosection in the teaching of anatomy Journal of Medical Education 45(8):600-606
The statistical results of this study indicate that there were no significant differences in students’ learning which could be attributed to the method of instruction, but that time could be saved if prosection, rather than dissection were to be adopted as the required laboratory procedure.
Despite students’ contention that they can learn more easily [via dissection], this was not borne out.

 |
…we have developed a computerized simulated dog head that can exhibit cranial nerve dysfunctions and respond to specific testing procedures in a clinically accurate manner. … In an experiment conducted with 97 freshman veterinary students who had recently been taught cranial nerve anatomy and function, we found that examination performance decreased with the need for interactivity compared to memorization of fact, while satisfaction increased. Students were less likely to identify the correct disorder when they had to conduct the examination of the virtual dog themselves, revealing an inadequacy in traditional neuroanatomical teaching. However, students overwhelmingly supported the use of interactive question for assessment. Interestingly, performance on text-based questions did not correlate significantly with interactive or video questions. The results have implications for veterinary teaching and assessment within the classroom and in clinical environments.

The results showed that the anatomical structures of the 3D-printed skulls were similar to the real skulls. There was no significant difference between the test scores of the students that did their test using the real skulls and those using 3D prints. In conclusion, it was possible to construct a dynamic and printed digital 3D collection for studies of the comparative anatomy of canine skull species from real skulls, suggesting that 3D-digitalized and-printed skulls can be used as tools in veterinary anatomy teaching.

This study compared the results of two training techniques, live-animal training and online video instruction…All participants were assessed on their ability to find and correctly name the four A-FAST quadrants on a live animal. We found a significant difference between the two groups in the students’ ability to identify the diaphragmatic-hepatic (DH) view, but for the other three views (hepatorenal, splenorenal, and cystocolic), training method did not affect performance. Results suggest the potential for using a multi-modal instructional approach to teach ultrasound techniques to veterinary students.

Provo, Judy A. and Lamar, Carlton, H. 1995 Prosection as an approach to student-centered learning in veterinary gross anatomy Journal of the American Veterinary Medical Association 206(2):158-161
By using prosections (as opposed to having each student or pair of students dissect their own cadaver) and increasing the number of students studying a particular cadaver, the overall number of animals used is decreased. No difference in learning is seen or demonstrable.
Analysis of performance in this course [in which prosection was compared with dissection] showed that veterinary students do not need to dissect every area to learn comparative anatomy effectively. Students made as many errors on structures that they learned by dissection as they did on structures learned from peer prosection. This finding is important for 2 reasons. First, learning by demonstration requires much less class time than does dissection (2 hours for a dissection assignment vs 20 to 30 minutes for a demonstration). Second, the use of prosections can reduce the number of animals needed to teach gross anatomy.
These findings are in agreement with those in human anatomy. …studies measuring retention have shown no difference between prosection and dissection.

Students’ performance on a practical neuroanatomy exam was compared, and no significant differences were found in scores based on the type of material (3D AM models or plastinated specimens) used for instruction. Students in both groups were equally able to identify neuroanatomical structures on cadaveric material, as well as respond to questions involving application of neuroanatomy knowledge. Therefore, we postulate that 3D AM canine brain models are an acceptable alternative to plastinated specimens in teaching veterinary neuroanatomy.

Tiplady, Catherine; Lloyd, Shan and Morton, John 2011 Veterinary science student preferences for the source of dog cadavers used in anatomy teaching Alternatives to Laboratory Animals 39(5):461-469
The authors demonstrate that students, although initially having ethical concerns about the source of cadavers, appear to lose this sensitivity as their exposure to consumptive use of animals increases.
These findings are consistent with the hypothesis that veterinary students become more accepting of the euthanasia of unwanted healthy animals for education as they progress through the veterinary programme, in contexts such as the current study. This could occur due to increased acceptance of the euthanasia of healthy animals generally, a decline in moral development, desensitisation, and/or the belief that healthy animal cadavers offer a superior learning experience.

With this educational support system, anatomical figures can be explained using living animals instead of specimens. In addition, clinical representative examples can be used to show anatomical disorders to students. … This system can enhance veterinary students’ understanding and interest in anatomy and can enable us to offer them a quality veterinary medical education. We concluded that CAD is a useful new option not only for clinical service but also for veterinary education.
