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.

Arising in carotid triangle [1]. Superior thyroid artery. Hyoid (infrahyoid) artery; Sternocleidomastoid artery; Superior laryngeal artery; Cricothyroid artery; Ascending pharyngeal artery
On the lateral side of the vessels, the accessory nerve runs for a short distance before it pierces the Sternocleidomastoideus; and on the medial side of the external carotid, just below the hyoid bone, the internal branch of the superior laryngeal nerve may be seen; and, still more inferiorly, the external branch of the same nerve.
The external branch functions to tense 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.
The recurrent laryngeal nerves are produced from the nerve of arch 5, and the laryngeal cartilages from arches 4 and 5. The superior laryngeal branch of the vagus nerve arises from arch 4. Its arteries, which project between the nerves of the fourth and fifth arches, become the left-side arch of the aorta and the right subclavian artery.
