ventricular fold of the larynx


ventricular fold of the larynx

The upper pair of ridges that project into the midsection of the larynx; these define the upper boundary of the laryngeal vestibule. Each fold is composed of pinkish mucosa covering a thin ligament (the vestibular ligament), which runs from the thyroid cartilage anteriorly to the arytenoid cartilage posteriorly, roughly parallel to the vocal ligament below it. The ventricular vocal folds contribute to certain types of sound production. Synonym: false vocal cordvestibular foldSee also: fold
