| medullary spinal arteries | A large caliber spinal or radicular artery which courses centrally along a dorsal or ventral root, perhaps supplying it and the surrounding meninges in the fashion of any spinal/radicular artery, but which continues on to reach and anastomose with the anterior or posterior (longitudinal) spinal artery. Only 4-9 of the spinal arteries are medullary spinal arteries, found mainly in the lower cervical, lower thoracic and upper lumbar levels, the largest of which is the great radicular artery.

| Charcot's arteries | Any one of a variety of small artery's entering the base of the brain through the anterior perforated substance and supplying the striatum, globus pallidus, and internal capsule; most of these perforating arteries are branches of the M1 segment (clinical terminology) of the middle cerebral and and (rarely) of the anterior choroidal artery.
