===Arterial Supply===
===Arterial Supply===
The spinal cord is supplied by three main arteries that run along its length; the '''Ventral Spinal Artery''', and paired '''dorsolateral spinal arteries'''. The ventral spinal artery is the largest and follows the ventral fissure of the spinal cord. The dorsolateral arteries run close to the groove from which the dorsal nerve roots arise. Together with these three main arteries, the spinal cord is also supplied by branches from regional arteries including branches in the cervical, intercostal, lumbar and sacral regions. These regional arteries enter the spine at the intervertebral foramina, often accompanying the roots of spinal nerves. These regional arteries also form plexuses into which the three main longitudinal arteries run.
