Medical Definition of Laryngeal nerves
1. Branches of the vagus nerve (the tenth cranial nerve). The superior laryngeal nerves originate near the nodose ganglion and separate into external branches, which supply motor fibres to the cricothyroid muscles, and internal branches, which carry sensory fibres. The recurrent (inferior) laryngeal nerve originates more caudally and carries efferents to all muscles of the larynx except the cricothyroid. The laryngeal nerves and their various branches also carry sensory and autonomic fibres to the laryngeal, pharyngeal, tracheal, and cardiac regions. (12 Dec 1998)
