Arteries of Spinal Cord: Schema Anatomy
Posterior cerebral artery, Superior
cerebellar artery, Basilar
artery, Anterior inferior cerebellar artery (AICA), Posterior inferior cerebellar artery (PICA), Anterior spinal artery,
Vertebral artery, Segmental medullary arteries, Ascending cervical artery, Cervical
vertebrae, Anterior view
Posterior view, Deep cervical
artery, Subclavian artery, Segmental medullary artery, Posterior
intercostal artery, Thoracic vertebrae, Pial plexus, Posterior
intercostal artery, Segmental medullary artery.
Lumbar artery, Anastomotic
loops to posterior spinal arteries Lumbar vertebrae, Lateral sacral artery: spinal branches Sacrum, Posterior
inferior cerebellar artery, Posterior
spinal arteries, Vertebral
artery, Segmental medullary arteries, Deep cervical artery, Ascending cervical artery, Subclavian artery, Segmental medullary arteries, Segmental medullary arteries, Posterior intercostal arteries, Anastomotic
loops to anterior spinal artery, Lumbar arteries, Lateral (or medial) sacral arteries, Note: All spinal nerve roots have associated radicular or segmental medullary arteries. Most roots have radicular arteries (see Plate 177). Both types of arteries run along roots, but radicular arteries end before reaching anterior or posterior spinal arteries; larger segmental medullary arteries continue on to supply a segment of these arteries. Anterior radicular artery (great radicular artery of Adamkiewicz).
