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 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 head and neck are emptied of blood by the subclavian vein and jugular vein. Right side of neck dissection showing the brachiocephalic, right common carotid artery and its branches The brachiocephalic artery or trunk is the first and largest artery that branches to form the right common carotid artery and the right subclavian artery .
Emissary veins have an important role in selective cooling of the head. They also serve as routes where infections are carried into the cranial cavity from the extracranial veins to the intracranial veins. There are several types of emissary veins including the posterior condyloid, mastoid, occipital and parietal emissary veins. [1]
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
The posterior auricular vein begins upon the side of the head, in a plexus which communicates with the tributaries of the occipital vein and the superficial temporal vein. It descends behind the auricle. [1] It joins the posterior division of the retromandibular vein. [1] It drains into the external jugular vein. [1] [2]
