in·ter·nal jug·u·lar vein

[TA]
main venous structure of the neck, formed as a continuation of the sigmoid sinus of the dura mater, contained within the carotid sheath as it descends the neck uniting, behind the sternoclavicular joint, with the subclavian vein to form the brachiocephalic vein.
Synonym(s): vena jugularis interna [TA]

internal jugular vein

one of a pair of veins in the neck. Each vein collects blood from one side of the brain, the face, and the neck, and both unite with the subclavian vein to form the brachiocephalic vein. Each internal jugular vein is continuous with the sigmoid in the posterior part of the jugular foramen at the base of the skull. Compare external jugular vein.

in·ter·nal jug·u·lar vein

(in-tĕr'năl jŭg'yū-lăr vān) [TA]
Main venous structure of the neck, formed as a continuation of the sigmoid sinus of the dura mater, contained within the carotid sheath as it descends the neck to unite, behind the sternoclavicular joint, with the subclavian vein to form the brachiocephalic vein.

internal jugular vein

A large vein in the neck, it drains the skull, brain, and parts of the face and neck. It originates in the jugular foramen at the base of the skull and descends vertically (behind the sternocleidomastoid muscle) in the carotid sheath. At its base, the internal jugular vein merges with the subclavian vein behind the clavicle to form the brachiocephalic vein.

The internal jugular vein is forms in the base of the skull by the merger of the inferior petrosal and sigmoid sinuses. As the vein descends through the neck, tributary veins include the facial, lingual, pharyngeal, superior thyroid, and middle thyroid veins.

The right internal jugular vein is often the blood vessel used for medical access to the central venous circulation and to the right side of the heart.
