The superior laryngeal nerve consists of two branches: the internal laryngeal nerve, which supplies sensory fibers to the laryngeal mucosa, and the external laryngeal nerve, which innervates the cricothyroid muscle. The superior laryngeal nerve innervates the two cr The superior laryngeal nerve arises from the middle of this ganglion. The nerve then combines with a branch from the superior cervical ganglion and runs downward alongside the pharynx and behind the internal carotid artery . The superior laryngeal nerve then divides into two branches: External branch.

On the left side, it arises on the left of the arch of the aorta, and winds below the aorta at the point where the ligamentum arteriosum is attached, and The recurrent laryngeal nerve (RLN) receives sensory innervation from the trachea, esophagus, and pyriform sinus before it enters the larynx deep into the inferior constrictor muscle and posterior to the cricothyroid articulation. The inferior thyroid artery and its branch, the inferior laryngeal artery, are responsible for blood supply to the RLN, which may pass anteriorly, posteriorly, or between the branches of the inferior thyroid artery. To sum up: The Nervus laryngeus recurrens innervates not only the larynx, but also the esophagus and the trachea and moreover “gives several cardiac filaments to the deep part of the cardiac plexus” etc. (the latter not shown below, but see quotations above).

Recurrent ble pasienter med reseksjon av nlr tid enn etter type 2 og hyppigere resulterte i permanente eller nervus vagus, ikke-rekurrerende nervus laryngeus, skader. The recurrent laryngeal nerve is a branch of the vagus nerve that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles.
