The aryepiglottic muscle is an intrinsic skeletal muscle of the throat.
The aryepiglottic muscle originates from the muscular process of arytenoid cartilage and inserts to the aryepiglottic fold and lateral perimeter of epiglottis. Aryepiglottic muscle is innervated by the inferior laryngeal nerve, a branch of the recurrent laryngeal nerve (a branch of the vagus nerve). The aryepiglottic muscle adducts arytenoid cartilages and serves as a sphincter on laryngeal inlet.
