Donating body to medical science

I'm probably going to shuffle off in the next 2-3 decades and thinking of what happens post death. I'm signed up as an organ donor, but thinking of donating my body to medical science. I have doctors and surgeons in the extended family and TBH i think setting fire to me is a bit if a waste(!)

I couldn't find anything national about a registry, so was looking for suggestions, pointers, advice etc on how to do that here?
