Meical terminology is a vocabulary for accurately describing the human body and associated components, conditions, processes and process in a science-based manner. This systematic approach to word building and term comprehension is based on the concept of: (1) Word roots, (2) prefixes, and (3) suffixes. The word root is a term derived from a source language such as Greek or Latin and usually describes a body part. The prefix can be added in front of the term to modify the word root by giving additional information about the location of an organ, the number of parts, or time involved. Suffixes are attached to the end of a word root to add meaning such as condition, disease process, or procedure.
