UPDATED: From the Greek [ep(i)] meaning "outer, above, or upon", and the Greek suffix [o-nym] meaning "name". The word [eponym] refers to a person's name becoming attached to an anatomical location or surgical procedure. For centuries it has been the custom to honor or remember someone by attaching their name to a structure, location, procedure, or maneuver.
This has changed as anatomists tend now to give locations and structures descriptive terms. An example of this would be the "Ampulla of Vater" named after the German anatomist Abraham Vater (1684-1751) described today in anatomical texts as the "hepatopancreatic ampulla". The controversy on using eponyms or not goes on...
