Arteries of vertebral column of one
Year-old infant - Arteries of lumbar part of vertibral canal, posterior view
The pedicles of the lumbar vertebrae have been transformed to permit the removal of the vertebral arches. The ramification of the spinal branches (6) of the lumbar arteries is similar to that in the thoracic region (211-4) in that transversely directed vessels arch across the posterior surface of the vertebral body, sending nutrient branches into the center of ossification and connecting with similar vessels of the opposite side. Ascending and descending communications with neighboring segmental arteries are consistently present. Great variation in the presence and size of radicular arteries is evident in the lumbar region also. The large radicular artery (5) that continues into the anterior spinal artery is the only sizeable vessel of this sort in the field of view.
