The laryngeal ventricle, (also called the ventricle of the larynx, laryngeal sinus, or Morgagni's sinus)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 vestibular ligament; 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
