Anatomical terminology

The occipital vein (vena occipitalis) is a vein located in the head that primarily drains the occipital region of the scalp. It is an important component of the venous drainage system of the head and neck.

Anatomy

The occipital vein originates from the occipital venous plexus, which is a network of small veins located in the occipital region. This plexus collects blood from the posterior part of the scalp and the superficial structures of the occipital area.

The occipital vein then travels inferiorly and anteriorly, passing through the trapezius muscle and the nuchal ligament. It eventually drains into the suboccipital venous plexus, which is situated in the suboccipital region, near the base of the skull.

Function

The primary function of the occipital vein is to drain deoxygenated blood from the occipital region of the scalp and convey it to the larger venous structures in the neck. This helps maintain proper blood circulation and pressure within the head and neck.

Clinical Significance

The occipital vein can be involved in various medical conditions, such as venous thrombosis or phlebitis. It may also be used as an anatomical landmark during surgical procedures involving the posterior scalp or the upper neck.
