jugular

 [jug´u-lar]
1. cervical (def. 1).
2. pertaining to a jugular vein.
3. a jugular vein.
jugular veins large veins that return blood to the heart from the head and neck; each side of the neck has two jugular veins, external and internal. The external jugular carries blood from the face, neck, and scalp and has two branches, posterior and anterior. The internal jugular vein receives blood from the brain, the deeper tissues of the neck and the interior of the skull. The external jugular vein empties into the subclavian vein, and the internal jugular vein joins it to form the brachiocephalic vein, which carries the blood to the superior vena cava, where it continues to the heart. If one of these veins is severed, rapid loss of blood will result and air may enter the circulatory system. In such a case, a compress should be applied to the wound with pressure. See anatomic Table of Veins in the Appendices and see color plates.

jugular veins

The six main veins-the right and left internal and external jugulars and the front anterior jugulars-that run down the front and side of the neck, carrying blood back to the heart from the head. The internal jugulars are very large trunks containing blood at low pressure. The external and anterior jugulars are much smaller.
