Medical terms

You should know all medical terms come from Ancient Greek and Latin. But the scientific word for each and most of them, which is used among doctors, medical schools and universities, is Greek. Of course I'm not capable of writing down the entire medical vocabulary but I will give you a satisfying example. Bear with me.
