Segmental medullary arteries are arteries of varying size in the thoracolumbar region that arise from segmental arteries of this region (
The largest anterior segmental medullary artery is known as the artery of Adamkiewicz.[citation needed]
Anatomy
Development
During embryological development, about 75% of the segmental medullary arteries regress, forming the thinner (anterior and posterior)
sensory ganglion of each spinal nerve); the remaining segmental medullary arteries persist to contribute arterial supply to the spinal cord, as well as giving rise to the aforementioned radicular arteries.[1]
