anterior jugular vein

The anterior jugular vein is a vein in the neck. It begins near the hyoid bone by the confluence of several superficial veins from the submandibular region.[1] It descends between the median line and the anterior border of the sternocleidomastoideus muscle, and, at the lower part of the neck, passes beneath that muscle to open into the termination of the external jugular vein, or, in some instances, into the subclavian vein https://en.wikipedia.org/wiki/Anterior_jugular_vein
