Artery: Superior laryngeal artery

Latin a. laryngea superior
Gray's subject #144 552

The superior laryngeal artery accompanies the internal laryngeal branch of the superior laryngeal nerve, beneath the Thyreohyoideus; it pierces the hyothyroid membrane, and supplies the muscles, mucous membrane, and glands of the larynx, anastomosing with the branch from the opposite side.
