Artery Laryngeal Middle

The middle laryngeal artery is an unpaired blood vessel, which is one of two branches extending from the aortic arch to the larynx. It is formed as a result of the division of the main trunk into the right and left laryngeal arteries. The middle laryngeal artery lies at the level of the cervical vertebrae C4 and C5, starting on the right side of this arch. It then passes down through the bodies of the first three cervical vertebrae.

The middle laryngeal artery is formed from large branches of the internal carotid artery directed to the pharynx. During its path, the artery passes through the collarbone, cricoid and thyroid cartilage ligaments. Along its path, the middle laryngeal artery branches into many small arteries that supply the tissues of the larynx, vocal cords and muscles surrounding the larynx. The branched artery is connected to the base of the larynx, passing through the beds of the cricoid and thyrohyoid joints. After passing through the last articular structure, the artery enters into connection with the hypoglossal artery, which is a branch of the external carotid artery.
