I have a question. I read an article of professor Tsuyoshi Awaya http://homepage1.nifty.com/awaya/hp/ronbun/r010.html
say:There are examples of the brain, liver, lungs, heart, bone, flesh, and fetus being utilized as medicine in Japan in past times.

I also read an article of John Z Bowers :Dissection of the human body was forbidden, and anatomical charts were inaccurate, based as they were on theory and casual observation of the dismemberment of a beheaded corpse after an execution. I have read this article http://wolfgangmichel.web.fc2.com/publ/aufs/64/64.htm
It is says:The dissection of human bodies was forbidden since it conflicted with the tenets of Buddhism.
However, Yamawaki and Genteki Kosugi (1734-91) managed to obtain permission from the authorities to perform a dissection.

My question is :From where they were taken (brain, liver, lungs, heart, bone, flesh) if dissection of human body was forbidden? They were taken only the bodies of criminal?

Yours sincerely.
