Thelaryngeal ventricle, (also called theventricle of the larynx,laryngeal sinus, orMorgagni's sinus)[1] is afusiformfossa, situated between thevestibular andvocal folds on either side, and extending nearly their entire length. There is also asinus of Morgagni in thepharynx.
The fossa is bounded, above, by the free crescentic edge of thevestibular ligament; below, by the straight margin of the vocal fold and laterally, by themucous membrane covering the correspondingthyroarytenoid muscle.
The anterior part of the ventricle leads up by a narrow opening into a pouch-likediverticulum, amucous membranous sac of variable size called theappendix of the laryngeal ventricle. The appendix (also called the laryngeal saccule, pouch or Hilton's pouch) extends vertically from the laryngeal ventricle. It runs between thevestibular fold, thyroarytenoid muscle, andthyroid cartilage, and is conical, bending slightly backward. It is covered in roughly seventymucous glands. The muscles surrounding the appendix compress it until mucus is secreted to lubricate the vocal folds.
