When I was forced to study science, we had to cut up frogs. Some found this enormously thrilling. I found it like trying to reason with a bank manager.
I was never asked, though, to cut up a human being. In Russia, however, schools seem not to distinguish between animals and humans.
For here is a delightful video of a science teacher slashing a student. The purpose was not dissection, but, one assumes, elucidation.
