Overview

In human anatomy, the anterior spinal artery is the blood vessel that supplies the anterior portion of the spinal cord. It arises from branches of the vertebral arteries and is supplied by the anterior segmental medullary arteries, including the artery of Adamkiewicz, and courses along the anterior aspect of the spinal cord.

The anterior spinal artery is a small branch, which arises near the termination of the vertebral, and, descending in front of the medulla oblongata, unites with its fellow of the opposite side at the level of the foramen magnum.

One of these vessels is usually larger than the other, but occasionally they are about equal in size.

The single trunk, thus formed, descends on the front of the medulla spinalis, and is reinforced by a succession of small branches which enter the vertebral canal through the intervertebral foramina; these branches are derived from the vertebral and the ascending cervical of the inferior thyroid in the neck; from the intercostals in the thorax; and from the lumbar, iliolumbar artery and lateral sacral arteries in the abdomen and pelvis.

They unite, by means of ascending and descending branches, to form a single anterior median artery, which extend as far as the lower part of the medulla spinalis, and is continued as a slender twig on the filum terminale.

This vessel is placed in the pia mater along the anterior median fissure; it supplies that membrane, and the substance of the medulla spinalis, and sends off branches at its lower part to be distributed to the cauda equina.

Disorders

Disruption of the anterior spinal cord leads to bilateral disruption of the corticospinal tract, causing motor deficits, and bilateral disruption of the spinothalamic tract, causing sensory deficits in the form of pain/temperature sense loss. See also Medial medullary syndrome
