The largest anterior segmental medullary artery is known as the artery of Adamkiewicz.
Anatomy
Development
During embryological development, about 75% of the segmental medullary arteries regress, forming the thinner (anterior and posterior) radicular arteries (which supply the two roots and 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.
