anterior jugular vein
The anterior jugular vein is a paired tributary of the external jugular vein.
It arises beneath the chin in the region of the hyoid bone or suprahyoid neck.
Origin and course
The anterior jugular vein has its origin as the confluence of several small superficial submandibular veins. It descends near the midline, medial to the anterior border of the sternocleidomastoid muscle and in its inferior path, superior to the sternum (in the suprasternal space), is connected to the contralateral anterior jugular vein by the jugular (venous) arch.
It terminates by passing deep to the clavicular head of the sternocleidomastoid muscle, to drain into the external jugular vein.
The vein often receives tributaries from:
- laryngeal veins
- small thyroid veins
It lies superficial to sternocleidomastoid and the infrahyoid (strap) muscles.
- it may drain into the subclavian vein directly
