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.
- This is an online program illustrating various aspects of anatomy.
Multi–detector row computed tomography (MDCT)
- Reported by Yamada et al 2007.
- Provides normal equine anatomy as well as diseases. From Web site:
A comprehensive exploration of the equine abdominal anatomy, the veterinarian’s approach to diagnosis, and detailed 3-D animations depicting more than 25 different diseases.

The following includes literature cited above or which is relevant to the issue of anatomy instruction. Some are older citations, demonstrating the usefulness of prosections and related issues. Some concern human medical school education, but the principle findings may have applicability to veterinary medical education. Others may not have practical application, but may be useful in developing arguments to promote humane alternatives by showing student preferences, student sensitivities and the world-wide nature of the concern for humane alternatives.

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.

The major conclusion of this study was that both methods are effective tools for technical skills training, but consideration should be given to the preferred learning style of adult learners to maximize educational outcomes.

…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.

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.

The method described in this study is a low-cost, user-friendly teaching tool that is potentially applicable across different academic disciplines and that can also be used to construct models of other systems and species. However, it should be combined with other anatomy teaching methods because it does not provide detailed representation of specific digestive system organ features.

Three-dimensional (3D) information plays an important part in medical and veterinary education. … 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.

- 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.

The fact that garments are amenable to palpation by large groups of students with no damage to the painting favors repeated use in hands-on wet labs. Garments such as the one described in this article introduce a novel approach to interdisciplinary teaching and learning, which can be combined with traditional anatomy teaching methods. … Steps in garment construction are highlighted and indications, advantages, and limitations of the method discussed.

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.
