The veins of the medulla spinalis (spinal veins, veins of the spinal cord) are situated in thepia mater and form a minute, tortuous, venous plexus.They emerge chiefly from the
median fissures of themedulla spinalis and are largest in thelumbar region .In this plexus there are:
* (1) two "median longitudinal veins", one in front of theanterior fissure , and the other behind theposterior 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 theinferior cerebellar veins , or in theinferior petrosal sinuses .External links
