Posterior spinal veins

Posterior Spinal Veins are a set of veins that are located in the spinal cord. They are responsible for draining blood from the posterior aspect of the spinal cord.

Etymology

The term "Posterior Spinal Veins" is derived from the Latin words "posterior" meaning "behind", "spinalis" meaning "of the spine", and "vena" meaning "vein".

Anatomy

The Posterior Spinal Veins are located in the posterior aspect of the spinal cord. They are paired veins that run longitudinally along the surface of the cord. They drain into the internal vertebral venous plexuses.

Function

The primary function of the Posterior Spinal Veins is to drain blood from the posterior aspect of the spinal cord. This includes the posterior columns and the posterior horns of the spinal cord.

Clinical Significance

Any damage or blockage to the Posterior Spinal Veins can lead to a condition known as spinal cord infarction, which is a stroke that occurs in the spinal cord. This can result in a variety of symptoms, including pain, weakness, and loss of sensation.
