"When swallowing, the aryepiglottic folds function as the chief protective airway mechanism1. The extensions of the thyroarytenoid muscle (thyroepiglottic muscle) adduct the aryepiglottic folds during swallow to prevent aspiration. When the larynx rises during the swallow, the epiglottis will often cover the laryngeal inlet as a protective mechanism 1. If coverage of the laryngeal inlet is deficient, laryngeal aspiration may ensue."
