The occipital vein is a vein of the scalp. It originates from a plexus around the external occipital protuberance and superior nuchal line to the back part of the vertex of the skull . It usually drains into the internal jugular vein , but may also drain into the posterior auricular vein (which joins the external jugular vein ).
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
The anterior part of it unites with the facial vein to form the common facial vein, which drains into jugular vein, and ultimately to the subclavian vein. The occipital vein terminates to the sub-occipital plexus. There are other veins, like the emissary vein and frontal diploic vein, which also contribute to the venous drainage.
The foramina in the base of the skull are exit and entry points for veins, arteries and cranial nerves. The cranial nerves as they exit through various foramina. Sphenoidal lingula; Subarcuate fossa; Dorsum sellae; Jugular process; Petro-occipital fissure; Condylar canal; Jugular tubercle; Tuberculum sellae; Carotid groove; Fossa hypophyseos ...

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
