Segmental medullary artery
Template:Short description Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters".Script error: No such module "Check for unknown parameters". Segmental medullary arteries are arteries of varying size in the thoracolumbar region that arise from segmental arteries of this region (posterior intercostal arteries or lumbar arteries) and pass through intervertebral foramina to supply the spinal cord.[1] They may join the anterior spinal artery.[2]
The largest anterior segmental medullary artery is known as the artery of Adamkiewicz.Script error: No such module "Unsubst".
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.[1]
