Internal jugular vein

Internal Jugular Vein

The Internal Jugular Vein (Pronunciation: In-ter-nal Ju-gu-lar Vain) is a paired vein that collects blood from the brain, face, and neck. The Internal Jugular Vein is the major vein in the neck, paired with the External Jugular Vein.

Etymology

The term "Internal Jugular Vein" is derived from the Latin words "jugulum" which means throat, and "vena" which means vein. The term "internal" is used to differentiate this vein from the External Jugular Vein, which is located more superficially in the neck.

Anatomy

The Internal Jugular Vein begins in the jugular foramen at the base of the skull, continuing down the neck, alongside the carotid artery, within the carotid sheath. It drains into the subclavian vein to form the brachiocephalic vein, which eventually becomes the superior vena cava, returning blood to the heart.
