The superior laryngeal nerve is a branch of the vagus nerve. It arises from the middle of the ganglion nodosum and in its course receives a branch from the superior cervical ganglion of the sympathetic.

It descends, by the side of the pharynx, behind the internal carotid artery, and divides into two branches:

• external laryngeal nerve
• internal laryngeal nerve
