Anterior jugular vein

Other Terms: Anterior external jugular vein, Vena jugularis anterior, Veine jugulaire antérieure

Description

The anterior jugular vein is usually found near the anterior margin of the sternocleidomastoid muscle. It arises beneath the chin upon the mylohyoid muscle. It is formed by the mental, submental, inferior labial, and inferior hyoid veins, and passes downward almost to the sternum, in advance of the anterior border of the sternocleidomastoid muscle, and resting on the sternohyoid muscle. Here it pierces the superficial layer of the deep cervical fascia, and occupies the interval above the sternum, made by the division of the superficial layer of the deep cervical fascia into two layers. It then turns laterally beneath the sternocleidomastoid muscle, and enters either the external jugular or the subclavian vein. It drains the skin and muscles of the anterior region of the neck. There are usually two anterior jugular veins, one upon each side of the median line of the neck, connected just above the sternum by a transverse branch, the jugular venous arch. This branch also occupies the interval between the two layers of the superficial layer of the deep cervical fascia. The anterior jugular vein contains no valves. It varies in size
