Radicular artery

The anterior and posterior radicular arteries are 32 pairs of small/[1] variously sized arteries that enter an intervertebral foramen,[2] bifurcating within it to form an anterior and a posterior radicular artery which accompany the anterior root and posterior root of a spinal nerve, respectively. They supply the corresponding spinal cord segment as well as the anterior and posterior root of the spinal nerve and its sensory ganglion (dorsal root ganglion).[1]

At the level of the lumbosacral enlargement, a relatively large radicular artery (the great radicular artery) that reaches the spinal cord is often present.[2]
