They don’t talk about all the potential uses for bodies that have been donated, because if people knew, they wouldn’t do it. Bodies directly donated to medical schools are likely used for training (educational dissections) and research, and sometime bits (e.g. bones) get harvested for transplants, but bodies that are undirected donations actually end up being handed over to an almost entirely unregulated for-profit industry, where they’re sold to anyone, and there’s a lot of uses that people wouldn’t be crazy about. E.g. getting shot and blown up by the military, being used for product testing, remains just getting dumped, etc. (Promises to families that remains will eventually be cremated and returned to them have no legal weight, so it often doesn’t happen.) Apparently funeral homes get a cut of the sales, so they’re motivated to mislead. Donors don’t realize they’re giving their bodies, for free, to be used as a commercial product.
My grandfather went to an agricultural school where they did human dissections (presumably as part of some veterinary training), and apparently they were local vagrants…
