The aryepiglottic muscle or aryepiglotticus muscle, often considered the aryepiglottic part of oblique arytenoid muscle, is an intrinsic muscle of the larynx.[1] It is a direct continuation of a portion of the fibers of the oblique arytenoid muscle, sharing its innervation and blood supply, after these select fibers travel laterally around the arytenoid apex to the aryepiglottic fold.[2]
The aryepiglottic muscle is innervated by the inferior laryngeal nerve, a branch of the recurrent laryngeal nerve (itself a branch of the vagus nerve).[2] Together with the oblique arytenoid muscle, it helps to act as a sphincter and weak adductor of the laryngeal inlet.[2]
