Lumbar arteries
The lumbar arteries are in series with the intercostals.
They are usually four in number on either side, and arise from the back of the aorta, opposite the bodies of the upper four lumbar vertebræ.
A fifth pair, small in size, is occasionally present: they arise from the middle sacral artery.
