The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere. It runs along the lateral sulcus [1] to empty into either the cavernous sinus, [1] [2] or sphenoparietal sinus. [1] It is adherent to the deep surface of the arachnoid mater bridging the lateral sulcus. It drains the adjacent cortex.
Terminations of the vasa recta form the straight venules, branches from the plexuses at the apices of the medullary pyramids. They run outward in a straight course between the tubes of the medullary substance and join the interlobular veins to form venous arcades. These in turn unite and form veins which pass along the sides of the renal pyramids.

The medullary interstitium is the tissue surrounding the loop of Henle in the medulla. It functions in renal water reabsorption by building up a high hypertonicity , which draws water out of the thin descending limb of the loop of Henle and the collecting duct system .
The efferent lymphatic vessel commences from the lymph sinuses of the medullary portion of the lymph nodes and leave the lymph nodes at the hilum, either to veins or greater nodes. It carries filtered lymph out of the node.

The veins of the brain, both the superficial veins and the deep venous system, empty into the dural venous sinuses, which carry blood back to the jugular vein and thence to the heart. In cerebral venous thrombosis, blood clots usually form both in the veins of the brain and the venous sinuses.
Radicular veins (or segmental medullary veins [citation needed]) are segmental veins providing venous drainage of the spinal cord and canal. They communicate with anterior and posterior spinal veins as well as epidural venous plexus. They exit the spinal canal through the intervertebral foramina, accompanying the corresponding of radicular ...
