Right external jugular vein

The right external jugular vein is a superficial vein of the neck that provides the primary venous drainage of the head into the right brachiocephalic vein, and subsequently into the cranial vena cava and the right atrium.

It is formed by the confluence of the maxillary and linguofacial veins (or the common facial vein, depending on the species), generally at the level of the angle of the mandible. It courses caudally within the jugular groove, which is bounded by the brachiocephalicus muscle laterally and the sternocephalicus muscle medially. It terminates at the thoracic inlet by joining the right subclavian vein to form the right brachiocephalic vein.
