The veins of the medulla spinalis (spinal veins, veins of the spinal cord) are situated in the pia mater and form a minute, tortuous, venous plexus.

They emerge chiefly from the median fissures of the medulla spinalis and are largest in the lumbar region.

In this plexus there are:
* (1) two "median longitudinal veins", one in front of the anterior fissure, and the other behind the posterior sulcus of the cord.
* (2) four "lateral longitudinal veins" which run behind the nerve roots.

They end in the intervertebral veins.

Near the base of the skull they unite, and form two or three small trunks, which communicate with the vertebral veins, and then end in the inferior cerebellar veins, or in the inferior petrosal sinuses.
