The 3rd and 4th lumbar veins drain into the inferior vena cava. [3]The fate of the two superior lumbar veins is far more variable, and may drain into either the inferior vena cava, ascending lumbar vein, azygos vein, or (on the left side) the left renal vein; the 1st lumbar vein often passes inferiorly to join the 2nd lumbar vein, but may less commonly drain into the ascending lumbar vein, or ...

It runs superiorly, intersecting with the lumbar veins as it crosses them. [1] It passes behind the psoas major muscle, but in front of the lumbar vertebrae. [1] When the ascending lumbar vein crosses the subcostal vein, it becomes one of the following: the azygos vein (in the case of the right ascending lumbar vein). [1] [2]

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 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 .
