Anterior jugular vein
The anterior jugular vein ("anterior jugular vein") is a paired, superficial vein of the neck.
The vein arises on the floor of the mouth and usually runs on the sternocleidomastoid muscle or the sternothyroideus muscle . In most cases, the right and left veins in the suprasternal space are connected by a venous arch, the jugular venous arc . The mouth is highly variable and is carried into the external jugular vein , internal jugular vein , subclavian vein or directly into the venous angle .
Compared to the other jugular veins of the neck (vena jugularis interna / externa), the vena jugularis anterior is usually much weaker and more variable in its course.
