There is no vein corresponding to the external carotid artery, but some veins from the face and scalp form the external jugular vein, which runs superficially over the sternomastoid muscle and pierces the deep fascia of the clavicle to enter the subclavian vein. Its tributary, the anterior jugular, runs down the front of the neck
The proximity of the jugular veins to the surface makes them liable to trauma with hemorrhage and aeroembolism.
Jugular venous pressure (JVP)Jugular venous pressure is the pressure in the internal jugular vein, which is an indirect measurement of central venous pressure (CVP) in the right atrium. In clinical practice the JVP is estimated by visual inspection at the bedside with the patient reclining at 45 degrees.
