Interior Jugular Vein
The internal jugular vein is a paired venous structure that collects blood from the brain superficial regions of the face and neck and delivers it to the right atrium.
Interior jugular vein. The largest pair of jugular veins are the internal jugular veins. The internal jugular vein is a paired jugular vein that collects blood from the brain and the superficial parts of the face and neck. Anatomically there are two of these veins that lie.
They are difficult to locate without ultrasound to assist. The internal jugular vein is a major blood vessel that drains blood from important body organs and parts such as the brain face and neck. Each of the internal jugular veins runs on either side of the neck under the sternocleidomastoid muscle.
It begins in the posterior compartment of the jugular foramen at the base of the skull. At approximately the level of the collarbone each unites with the subclavian vein of that side to form the innominate veins. While the left internal jugular vein is closer to the carotid artery to the extent that it overlaps there is some distance between the right internal jugular vein and the common carotid artery.
The internal jugular vein is a run off of the sigmoid sinus. The internal jugular veins are paired veins that are placed laterally to the carotid artery on either side of the neck. This vein runs in the carotid sheath with the common carotid artery and vagus nerve.
