Anatomical terminology

The ventricle of the larynx (also called the laryngeal sinus, laryngeal ventricle or Morgagni's sinus)[1] is a fusiform fossa, situated between the ventricular and vocal folds on either side, and extending nearly their entire length. There is also a sinus of Morgagni in the pharynx.

The fossa is bounded, above, by the free crescentic edge of the ventricular fold; below, by the straight margin of the vocal fold and laterally, by the mucous membrane covering the corresponding thyroarytenoid muscle.

The anterior part of the ventricle leads up by a narrow opening into a pouch-like sac of mucous membrane of variable size called the appendix.
