The veins of the right half of the male pelvis (lumbar arteries not labeled, but third lumbar vein labeled at center top)
|Latin||Arteriae lumbares Arteriae lumbales|
A fifth pair, small in size, is occasionally present: they arise from the middle sacral artery.
They run lateralward and backward on the bodies of the lumbar vertebrae, behind the sympathetic trunk, to the intervals between the adjacent transverse processes, and are then continued into the abdominal wall.
They now cross the quadratus lumborum, the upper three arteries running behind, the last usually in front of the muscle.
