A brief review of the innervation of the larynx will show that all of the muscles of the larynx, with the exception of the cricothyroid, which is supplied by the superior laryngeal nerve, are supplied by the recurrent laryngeal nerve, often called the motor nerve of the larynx. The recurrent laryngeal nerve, it will be recalled, has its origin in the medulla oblongata on the floor of the fourth ventricle, leaves the cranial cavity in the trunk of the vagus nerve and is contained in this nerve until it has entered the thorax; here the recurrent laryngeal nerve follows a different course on each side.

On the right side it leaves the vagus nerve just in front of the subclavian artery, winds backward around that vessel and ascends obliquely to the side of the trachea behind the common carotid artery, and either posterior to or anterior to the inferior thyroid
