In human anatomy, the anterior spinal artery is the artery that supplies the anterior portion of the spinal cord.It arises from branches of the vertebral arteries and courses along the anterior aspect of the spinal cord.
The anterior portion of the spinal cord is supplied by the anterior spinal artery. It begins at the foramen magnum where branches of the two vertebral arteries exit, merge, and descend along the anterior spinal cord. As the anterior spinal artery proceeds inferiorly, it receives branches originating mostly from the aorta. [1]
The spinal cord is supplied with blood by three arteries that run along its length starting in the brain, and many arteries that approach it through the sides of the spinal column. The three longitudinal arteries are the anterior spinal artery, and the right and left posterior spinal arteries. [11]
At each cervical level, the vertebral artery sends branches to the surrounding musculature via the anterior spinal arteries. Segments of vertebral artery anterior projection. The vertebral artery may be divided into four parts: The first (preforaminal) part runs upward and backward between the anterior scalene and the longus colli muscles.

The artery provides blood supply to the front two-thirds of the lumbar and sacral cord. [13] When damaged or obstructed, it can result in a syndrome of spinal cord ischemia, similar to anterior spinal artery syndrome, [14] with loss of urinary and fecal continence and impaired motor function of the legs; sensory function is often preserved to a ...

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.
