The Jewish belief in the inviolability of the human body is reflect ed in its attitude to post-mortem examinations. The Talmud (San hedrin 47a) asserts that the biblical imperative of speedy burial (Deuteronomy 21:22-23) is based upon the prohibition of disgrac ing a corpse. The scope of this prohibition extends beyond delayed burial. Scripture proscribes the inflicting of any form of disgrace upon a corpse. In general, this includes the disfigurement of the body as a result of post-mortem dissection (autopsy).
note the use of the term "post-mortem dissection". In my view anyone writing on this subject should always use this term as it will increase public unease about this practise.

although some other sections of the article are more sympathetic to those who dissect dead bodies to earn money.

which unfortunately perpetuates the use of the misleading word "examination". Most people would think that if you examine something this doesn't include cutting it open with a power saw and ripping the parts out of it.
