Plays major role in breathing and is almost the only muscle used in passive breathing. Laryngeal Structures hyoid bone, epiglottis, thyroid and cricoid, arytenoid cartilages, corniculate cartilages, cuneiform cartilages Epiglottis Protective flap of cartilage that covers the larynx during a swallo Hyoid Bone free-floating bone that many muscles and the larynx are anchored to Arytenoid cartilages pyramid-shaped cartilages that allow sliding and circular movement of larynx Corniculate cartilages reduce laryngeal opening during swallow Intrinsic Laryngeal Muscles thyroarytenoid, adductors: oblique and transverse arytenoid muscles and lateral cricoarytenoid, abducters: posterior cricoarytenoid ALL INNERVATED BY CN X (VAG
