Anatomical terminology
Anatomical terminology is used by anatomists and zoologists, in scientific journals, textbooks, and by doctors and other health professionals. Anatomical terminology contains a variety of unique and possibly confusing terms to describe the anatomical location and action of different structures. By using this terminology, anatomists hope to be more precise and reduce errors and ambiguity. For example, is a scar ""above the wrist"" located on the forearm two or three inches away from the hand? Or is it at the base of the hand? Is it on the palm-side or back-side? By using precise anatomical terminology, ambiguity is eliminated.Anatomical terms derive from Ancient Greek and Latin words, and because these languages are no longer used in everyday conversation, the meaning of their words does not change. The current international standard is the Terminologia Anatomica.
