Anterior jugular vein

Anterior Jugular Vein

The anterior jugular vein, as depicted in Gray's Anatomy.

The anterior jugular vein is a vein located in the neck that collects blood from the inferior part of the face and the neck. It is a part of the jugular venous system.

Structure

The anterior jugular vein originates from the submandibular region, near the hyoid bone. It descends in the neck, superficial to the sternocleidomastoid muscle, and drains into the external jugular vein or the subclavian vein. The two anterior jugular veins are often connected by a transverse trunk, the jugular venous arch, which lies above the sternum.

Function

The anterior jugular vein is responsible for draining blood from the face and neck. It also plays a role in the regulation of cerebral blood flow.

Clinical significance

Due to its superficial location, the anterior jugular vein is often used for central venous catheterization. It can also be affected by various medical conditions, such as jugular vein thrombosis and jugular vein distention.
