| Anatomical terms of muscle | |
The muscle originates from the muscular process of arytenoid cartilage and inserts to the aryepiglottic fold and lateral border 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 muscle adducts arytenoid cartilages and acts as a sphincter on laryngeal inlet.[1][2]
