Anatomical terminology |
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.[1]
It varies considerably in size, bearing usually an inverse proportion to the external jugular; most frequently there are two anterior jugulars, a right and left; but sometimes only one.[1]
Its tributaries are some laryngeal veins, and occasionally a small thyroid vein.[1]
Just above the sternum the two anterior jugular veins communicate by a transverse trunk, the venous jugular arch, which receive tributaries from the inferior thyroid veins; each also communicates with the internal jugular.[1]
There are no valves in this vein.[1]
