The spinal veins (veins of the medulla spinalis or 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:

Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
The most efficient way to study the spinal venous system along with the anterior spinal veins is to do it postmortem. These types of studies give an effective anatomical demonstration of how the system works. One of the few major studies of the venous anatomy was conducted by Armin Thron, which can be seen in his published “Vascular Anatomy ...

In human anatomy, the cephalic vein (also called the antecubital vein) [1] is a superficial vein in the arm. It is the longest vein of the upper limb. It starts at the anatomical snuffbox from the radial end of the dorsal venous network of hand, and ascends along the radial (lateral) side of the arm before emptying into the axillary vein.
Perforator veins play a very special role in the venous system, carrying blood from superficial to deep veins. During the muscular systole their valves close and stop any blood flow coming from the deep to the superficial veins. When their valves become insufficient, they are responsible for a rapid deterioration in existing varicose disease ...
