Suboccipital venous plexus

From Wikipedia, the free encyclopedia

Vein: Suboccipital venous plexus
Latin	plexus venosus suboccipitalis
Source	occipital vein
Drains to	vertebral vein

The Suboccipital Venous Plexus drains the back of the head.

It communicates with the external vertebral venous plexuses. The external vertebral venous plexuses travel inferiorly from this suboccipital region to drain into the brachiocephalic vein. The occipital vein joins in the formation of the plexus deep to the musculature of the back and from here drains into the external jugular vein.

The plexus surrounds segments of the vertebral artery.
