Cricoarytenoid joint explained

Cricoarytenoid joint
Latin:articulatio cricoarytaenoidea
System:larynx

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. The extent of rotation is significant, while the extent of gliding is limited.

The cricoarytenoid joint controls the abduction and adduction of the vocal cords. It is moved by many of the intrinsic muscles of the larynx.[2]

History

The cricoarytenoid joint was first described by Galen.[3]
