Laryngeal nerve

Laryngeal nerve

The Laryngeal nerve, or Galen's nerve, is a nerve originating from the vagus nerve. It comprises two branches, the cranial [superior laryngeal nerve] , which leaves the vagus at the distal ganglion and passes ventrally to the larynx supplying the cricothyroid muscle and laryngeal mucosa, and the caudal [recurrent laryngeal nerve] , which enters the larynx under the caudal edge of the cricopharyngeaus muscle and innervates all of the muscles of the larynx except the cricothyroideus.

There are two subdivisions of the cranial laryngeal nerve. These are internal (sensory) and external (motor).
