| Anatomical terminology | |
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. They may join the anterior spinal artery.
The largest anterior segmental medullary artery is known as the artery of Adamkiewicz.
