Abstract
While debate about the use of-and alternatives to-human cadaveric dissection in medical training is robust, little attention has been paid to questions about timing. This study explores the perspectives of medical students and recent graduates with regard to two key questions: when in the degree program do students prefer dissection opportunities and what are the students getting out of participating in dissection? Self-report survey data from students in preclinical years (n = 105), clinical years (n = 57), and graduates (n = 13) were analyzed. Most (89%) preferred dissection during the preclinical years, with no effect by training year (χ2 = 1.98, p = 0.16), previous anatomy (χ2 = 3.64, p = 0.31), or dissection (χ2 = 3.84, p = 0.26) experience. Three key findings emerged. First, the majority of students prefer to dissect in the preclinical years because they view dissection as important for developing foundation knowledge and delivering an opportunity for consolidation prior to transitioning to primarily clinical studies. In addition, students recognize that it is a time-consuming activity requiring specialized facilities. Second, three main understandings of the purpose of dissection were reported: depth of learning, learning experience, and real-world equivalence. Third, these student perspectives of the purpose of dissection are associated with timing preferences for dissection opportunities. The results identify the preclinical phase as the optimal time to strategically integrate dissection into medical training in order to maximize the benefits of this unique learning opportunity for students and minimize its impact upon curricular time.Entities:

Summary of overarching and subthemes in the descriptions of rationale to conduct dissection during the preclinical years by medical students and recent graduates
| Understanding of the role of dissection | Main themes of rationales | Examples of student responses |
|---|---|---|
| Dissection as a foundational exercise in getting to grips with anatomical knowledge (mentioned by 67% of respondents) |
Dissection as a component of learning anatomy‐key modality for the study of anatomy to be undertaken whilst studying lectures, practicals etc. Dissection as fundamental foundation—essential to acquire this experience early as a foundation for other learning experiences Preparation for clinical training—essential experience prior to clinical studies in later years of the program |
“Complement lectures” (Y1) “It will be close in timing to the lectures” (Y1) “To coincide with learning anatomy” (G) “Anatomy underpins a lot of what we are learning; good to get a handle on it as early as possible” (Y1) “Being exposed to dissections earlier will help contextualise knowledge” (Y2) “Anatomy is an important foundation subject in medicine and it would really help a lot with learning if dissection is done early on” (Y3) “To obtain a strong understanding of human anatomy before starting a clinical training regime” (Y1) “It'll give a good background before entering the clinical years” (Y2) “Useful to have anatomical basis before clinical years” (Y4) |
| Dissection as a tool for revising, consolidating and applying anatomical knowledge (mentioned by 57% of respondents) |
Consolidation—key time to consolidate previously learnt anatomy Relevance—linked to/relevant to other disciplines studied concurrently |
“I think people would benefit from having dissection as a way to consolidate all of the information” (Y1) “If we continued to dissect as we learnt the anatomy of different regions it we could see how all the systems work together and allow us to learn more effectively as we go” (Y2) “It seems like we learnt so much anatomy in the first few weeks of year one, so it would be good to then apply this and reinforce this knowledge” (Y2) “Best done at the time to consolidate learning” (Y3) “After learning core anatomy and the fundamentals in physiology it's a great time to do some dissecting to tie it all together” (Y4) “Anatomy underpins a lot of what we are learning; good to get a handle on it as early as possible” (Y1) “Learning about basic anatomy would align well with the other basic sciences we need to learn in the first 2 years and allow greater integration” (Y2) “To get a good understanding of anatomy as we were exposed to it block by block matching the clinical examinations learnt during clinical days” (G) |
| Dissection as a time‐consuming activity that requires specialized facilities (mentioned by 42% of respondents) |
Focus on time (workload)—due to student curricular availability, conflicting activities and priorities Focus on location (convenience)—due to primary location of students and facilities |
“Time availability” (Y1) “Less busy with clinical work” (Y1) “More time and less pressure. Year 3 and 4 clinical commitments would make it difficult to spend the time” (Y4) “Dissection is time consuming and should not interfere with clinical time in the hospital” (Y4) “It is easier to coordinate when we are on campus” (Y1) “We are based on campus” (Y2) “Years 3 and 4 are at the hospital and very busy” (Y2) “Easier to perform during laboratory hours while on university campus” (Y4) |
Percentages will not sum, as some responses covered multiple themes.

Summary of overarching and subthemes in the descriptions of perceptions of the value of dissection by medical students and recent graduates
| Perception of the value of dissection | Main subthemes | Examples of student responses |
|---|---|---|
| The learning experience itself |
Mode of learning: hands‐on, interactive, effective Unique and/or novel learning modality Active learning |
“Hands on experience, future desire to be a surgeon” (Y1) “It will provide another way to learn anatomy‐a very powerful way” (Y1) “It would be beneficial as you could take your time and cement your anatomy learning by actively taking part in the study of anatomy, rather than observing” (Y2) |
| Depth and type of knowledge |
Deep learning: better understanding, integration, structural relationships, consolidation, more details, better comprehension Understanding function and relationships |
“It would allow us to integrate our knowledge of all the systems learnt so far” (Y2) “Better understanding of anatomy in general and the positioning/connections of organ and tissues within body” (Y1) “Gain greater insight into how structures are interconnected and function” (Y1) |
| Skill acquisition |
Technical skill Surgical relevance |
“To become more familiar with the human anatomy and to build confidence in surgical procedures” (Y1) “Because it's a valuable learning experience and the closest thing to a surgery that we will do for a long time” (Y1) |
| Real‐world equivalence |
Realistic learning‐ abnormality, variation Ability to see pathology |
“It makes all of the pictures you see in a textbook so much more realistic!—even the texture of the parts of the cadaver could help in our understanding of body parts” (Y2) “Appreciate anatomy from a whole‐cadaver perspective, spending time to locate the anatomical features under the direction of an instructor would allow you to appreciate anatomical variation and apply clinical concepts; appreciate effects of pathology” (Y2) |
| Perception of no value |
Negative previous experience Personal feelings |
“I have past dissection experience and I feel you can gain the same info with excellent preparation, tutors and looking at models” (Y1) |
