aryepiglottic fold
Quick Summary
The aryepiglottic folds are mucous membrane folds that extend from the apex of the arytenoids to the lateral margin of the epiglottis. These folds, along with the aryepiglotticus muscle, help narrow the laryngeal vestibule by pulling the arytenoids together and the epiglottis downward. This action contributes to the protective sphincter function of the larynx, which closes the airway during swallowing. The aryepiglottic folds are part of the structure of the larynx, which also includes cartilages, muscles, nerves, blood vessels, and membranes.12
