Clinical Anatomical Terminology Committee
The Clinical Anatomical Terminology (CAT) Committee of the AACA investigates the usage of clinical anatomical terminology and actively promotes dissemination of equivalent clinical and anatomical terms for identical anatomical structures or concepts through the development and maintenance of free web-based resources and through regular publications in the Association’s journal, Clinical Anatomy.
The Committee is responsible for planning and implementing a Clinical Anatomical Terminology Symposium when scheduled by the Meeting Oversight and Program Planning Committee.
The Committee consists of thirteen (13) members, each serving a three (3) year term. The President-Elect appoints two (2) members in the second year of their term, and the President appoints two (2) members in the first year of their term. Two members are to be nominated and elected by the Active Members in attendance at the CAT Committee’s annual open meeting. A Clinical Councilor is designated by the President and serves as an ex officio member of the CAT Committee. The Chair shall be appointed by the incoming President and shall serve for a period of two (2) years. Appointed members will serve for two (2) years, while elected members will serve for three (3) years.
