The external branch functions to stretch the vocal cords by activating the cricothyroid muscle, increasing pitch. The external laryngeal nerve gives branches to pharyngeal plexus and the superior portion of the inferior pharyngeal constrictor, and communicates with the superior cardiac nerve behind the common carotid artery.
This artery branches from the superior thyroid artery near its bifurcation from the external carotid artery. Together with the internal laryngeal nerve , it pierces the lateral thyrohyoid membrane , and supplies blood to the muscles, mucous membrane , and glands of the larynx , connecting with the branch from the opposite side.

Its lateral thinner portions are pierced by the superior laryngeal vessels and the internal branch of the superior laryngeal nerve. [1] Its anterior surface is in relation with the thyrohyoid muscle, sternohyoid muscle, and omohyoid muscles, and with the body of the hyoid bone. It is pierced by the superior laryngeal nerve. [2]

In about four people out of five, there is a connecting branch between the inferior laryngeal nerve, a branch of the RLN, and the internal laryngeal nerve, a branch of the superior laryngeal nerve. This is commonly called the anastomosis of Galen ( Latin : ansa galeni ), even though anastomosis usually refers to a blood vessel , [ 12 ] [ 13 ...
It is innervated by the pharyngeal plexus and by the recurrent laryngeal nerve. The vascular supply to the laryngopharynx includes the superior thyroid artery, the lingual artery and the ascending pharyngeal artery. The primary neural supply is from both the vagus and glossopharyngeal nerves.
