The dorsal cricoarytenoid muscle is innervated by the '''caudal laryngeal nerve''', a branch of the vagus nerve ([[Cranial Nerves - Anatomy & Physiology|CN X]]). It runs from the dorsal surface of the '''cricoid cartilage''' to the '''arytenoid cartilage'''. It abducts the vocal process and therefore the vocal fold to widen the glottis.
