Origin

The superior laryngeal artery arises from the superior thyroid artery, the first branch of the external carotid artery.

Course

The superior laryngeal artery extends medially and deep to the thyrohyoid muscle. It pierces through the thyrohyoid membrane to enter the larynx. It is accompanied by the internal laryngeal nerve.

Branches

There are no named branches of the superior laryngeal artery; however, it forms an anastomosis with the inferior laryngeal branch of the inferior thyroid artery. Additionally, the superior laryngeal artery forms an anastomosis with its fellow branch from the opposite side.

Supplied Structures

The superior laryngeal artery supplies the tissues of the upper part of the larynx.
