lumbar artery
anatomy
Quick Summary
The lumbar arteries are part of the human arterial system, which transports blood from the heart to the rest of the body. These arteries arise from the abdominal aorta, which is the portion of the aorta located in the abdominal cavity. The lumbar arteries are arranged in four pairs and supply blood to the muscles of the abdominal wall, the skin, the lumbar vertebrae, the spinal cord, and the meninges (the protective coverings of the spinal cord).12
