Jugular Vein Anatomy

Internal jugular vein special features. It is dilated at two places which are referred to as the superior bulb and the inferior bulb.

Internal Jugular Vein Anterior Jugular Vein External Jugular

The main vessels are the external jugular vein and the interior jugular vein.

Jugular vein anatomy. It descends in the carotid sheath with the internal carotid artery. The vein runs in the carotid sheath with the common carotid artery and vagus nerve. The internal jugular vein ijv is the major venous return from the brain upper face and neck.

There are two sets of 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. The jugular veins are veins that bring deoxygenated blood from the head back to the heart via the superior vena cava.

It is continuous with the transverse sinus which is a dural venous sinus. Transverse process of atlas. 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. At its distal end the external jugular vein perforates the deep neck fascia and terminates in the subclavian vein. The external jugular vein starts in the parotid at the level of the angle of the mandible and runs vertically down the neck along the posterior border of the sternocleidomastoid muscle.

Anatomically there are two of these veins that lie along each side of the neck. 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. Jugular vein any of several veins of the neck that drain blood from the brain face and neck returning it to the heart via the superior vena cava.

It is formed by the union of inferior petrosal and sigmoid dural venous sinuses in or just distal to the jugular foramen forming the jugular bulb. External and internal. First at its orgin point which is located at the jugular fossa.

Both connect to the brachocephalic veins the external jugular joining more laterally than the internal. The external jugular vein varies in size bearing an inverse proportion to the other veins of the neck it is occasionally double. The anterior jugular vein is a related vein which is formed from submandibular veins and can drain into the external jugular vein or the subclavian vein 9.

The internal jugular vein emerges from the posterior of a large aperture called jugular foramen which is located at the base of the skull. They each rest beside the thyroid gland at the center of the neck just above the collarbone and near the trachea or windpipe. The external jugular vein most commonly drains into the subclavian vein near the middle third of the clavicle.

Inferior petrosal vein is typically the very first tributary and joins.
