Why are all medical terms and names, named with greek words?
Actually, most medical terms are named with Latin words. The reason for this (also the reason for the Greek, when there is greek) is because most medical doctors in Europe from the Middle Ages through to the end of the 19th century were classically trained when they were at school, so as 12-year-olds they had to learn Latin and Greek. Latin, especially, was simply the language of scholarship; they thus wrote their treatises in Latin and gave anatomical parts Latin names (ulna, patella) with some Greek thrown in (metatarsal). In those days, the Classical languages served the function that English serves today: it was an international language of scholarship that allowed people from across the continent and around the world to communicate with one another in a common tongue. Since anatomy and epidemiology arose at the same time that Latin and Greek were being taught in schools in this way, naturally many of the terms associated with those fields came out of Latin and Greek roots.
