The posterior commissure of the larynx is a name often given to the posterior portion of the glottis. The interarytenoid muscles are part of this anatomical landmark.

Terminology

The term 'commissure' is a misnomer as the true vocal cords do not join together posteriorly to form a commissure ^3,4. It is sometimes referred to as posterior portion of the glottis, posterior wall of the glottis or posterior end of the glottis ^2-4.
