Vertebral vein

From Wikipedia, the free encyclopedia

Vein: Vertebral vein

The vertebral vein. (Vertebral labeled at upper left and center right.)
Latin	v. vertebralis
Gray's	subject #168 649
Source	deep cervical vein
Drains to	brachiocephalic vein
Artery	vertebral artery

The vertebral vein is formed in the suboccipital triangle, from numerous small tributaries which spring from the internal vertebral venous plexuses and issue from the vertebral canal above the posterior arch of the atlas.

They unite with small veins from the deep muscles at the upper part of the back of the neck, and form a vessel which enters the foramen in the transverse process of the atlas, and descends, forming a dense plexus around the vertebral artery, in the canal formed by the foramina transversaria of the cervical vertebrae.

This plexus ends in a single trunk, which emerges from the foramen transversarium of the sixth cervical vertebra, and opens at the root of the neck into the back part of the innominate vein near its origin, its mouth being guarded by a pair of valves.

On the right side, it crosses the first part of the subclavian artery.
