UPDATED: From the Greek, the prefix [ana-] meaning "trough" or "up", the root term [-tom-], arising from [τομή] (tom??) meaning "to cut", and the suffix [-y], meaning "process". The word [anatomy] means then, "a process of cutting up", a very good description of what anatomists do. What is interesting is that the word anatomy describes an action, and as such can be used as a verb. It is correct to say "to anatomize" when referring to the act of dissecting a body or body part.
The word "anatomy" has the same meaning as "dissection", a word with Latin roots. The prefix [dis-] means "apart", while the root term [-section] means "to cut". [-section] arises from the Latin [sectis] or [secare]. both meaning "to cut".
Today the term [anatomy] is used to describe one of the basic medical sciences; in the Middle Ages the terms to "dissect" or to "anatomize" were interchangeable.
Anatomy is "the study of the human body, its parts and components, and the spatial relationship between this components". For many, anatomy is at the basis of the Science of Surgery
There are many subspecialties in anatomy, including:
• Gross anatomy: That anatomy that can be seen with the naked eye
Personal note: The improper pronunciation of the term [dissection] is one of my pet peeves!
