Radicular artery

The anterior and posterior radicular arteries are 32 pairs of small/ variously sized arteries that enter an intervertebral foramen, 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.
