Definition
Noun: 1. Lumbar Artery: One of a series of paired arteries, typically four or five on each side, that branch from the back (posterior) surface of the abdominal aorta. These arteries supply oxygenated blood to the muscles and skin of the lower back (lumbar region), the spinal column (vertebrae), the spinal cord and its membranes (meninges), and the posterior abdominal wall.
Usage
