Vein: External jugular vein
Veins of the head and neck. (External jugular visible at center.)
Veins
Latin	vena jugularis externa
Gray's	subject #168 646
Drains from	cranium, face
Source	posterior facial vein, posterior auricular vein, anterior jugular vein
Drains to	subclavian vein
MeSH	Jugular+Veins

The external jugular vein receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.

Path

It commences in the substance of the parotid gland, on a level with the angle of the mandible, and runs perpendicularly down the neck, in the direction of a line drawn from the angle of the mandible to the middle of the clavicle at the posterior border of the sternocleidomastoideus.

In its course it crosses the sternocleidomastoideus obliquely, and in the subclavian triangle perforates the deep fascia, and ends in the subclavian vein lateral to or in front of the scalenus anterior, piercing the roof of the posterior triangle.

It is separated from the sternocleidomastoideus by the investing layer of the deep cervical fascia, and is covered by the platysma, the superficial fascia, and the integument; it crosses the cutaneous cervical nerve, and its upper half runs parallel with the great auricular nerve.

The external jugular vein varies in size, bearing an inverse proportion to the other veins of the neck, it is occasionally double.

The external jugular vein drains into the subclavian vein lateral to the junction of the subclavian vein and the internal jugular vein.

Valves

It is provided with two pairs of valves, the lower pair being placed at its entrance into the subclavian vein, the upper in most cases about 4 cm above the clavicle. The portion of vein between the two sets of valves is often dilated, and is termed the sinus.

These valves do not prevent the regurgitation of the blood, or the passage of injection from below upward.

Tributaries

This vein receives the occipital occasionally, the posterior external jugular, and, near its termination, the transverse cervical, transverse scapular, and anterior jugular veins; in the substance of the parotid, a large branch of communication from the internal jugular joins it.
