Blood Vessels of the Spinal Cord in a Transparent Male Body, Posterior View

Description

Seen from a posterior perspective in a transparent adult male body, the vertebral column frames the spinal cord as it descends from the cervicomedullary junction toward the conus medullaris, with paired posterior (dorsal) spinal arteries tracking longitudinally along the dorsolateral surface. Segmental radicular arteries enter with the dorsal roots through the intervertebral foramina, then reinforce the pial arterial network (vasocorona) around the cord. Blue-highlighted posterior spinal veins course parallel to the arteries and receive tributaries from the dorsal surface before draining toward the internal vertebral venous plexus. Nerve roots radiate laterally, with dorsal rootlets positioned posterolaterally relative to the cord and the vertebral laminae and spinous processes forming the posterior bony boundary. Posterior spinal cord vascular anatomy matters when you are localizing spinal cord infarction patterns and differentiating them from compressive myelopathy, because dorsal column ischemia follows a different clinical script than anterior spinal artery syndrome. A posterior view also clarifies how radiculomedullary feeders accompany nerve roots, a point that becomes concrete during thoracolumbar surgery or endovascular work when a segmental artery must be sacrificed or selectively catheterized. Small vessels, big consequences. Use this illustration in gross anatomy and neuroanatomy teaching to pair dorsal root entry zones with the posterior spinal arterial and venous drainage patterns, and in neurosurgery, orthopedic spine, and neuroradiology materials discussing laminectomy corridors, spinal dural arteriovenous fistula, or postoperative venous congestion. It also fits textbook figures on spinal cord blood supply, radicular reinforcement, and the relationship between vertebral anatomy and neurovascular pathways.
