Cricoarytenoid joint
The cricoarytenoid joint is a joint connecting the cricoid cartilage and the arytenoid cartilage. It is a very shallow ball-and-socket joint. It allows for rotation and gliding motion. This controls the abduction and adduction of the vocal cords.

Structure
The cricoarytenoid joint is a very shallow ball-and-socket joint.[1]
Function
The cricoarytenoid joint allows for rotation and gliding motion.[1] The extent of rotation is significant, while the extent of gliding is limited.[1]
The cricoarytenoid joint controls the abduction and adduction of the vocal cords.[1] It is moved by many of the intrinsic muscles of the larynx.[2]
History
The cricoarytenoid joint was first described by Galen.[3]
