Blood Vessels of the Spinal Cord of a Transparent Male

Description

Running within a transparent male torso, the spinal cord sits centrally in the vertebral canal with paired spinal nerve roots exiting laterally toward the lumbar plexus. Along the anterior median fissure, the anterior spinal artery descends in the midline, while paired posterior spinal arteries track on the dorsolateral surface near the dorsal root entry zones. Segmental radicular arteries accompany the ventral and dorsal roots through the intervertebral foramina, feeding a pial vasocorona that encircles the cord, and the efferent venous network mirrors this arrangement with anterior and posterior spinal veins draining toward radicular veins. Spatial relationships are clear. Midline vessels remain medial, radicular channels angle laterally, and plexiform veins surround the neural tissue in a sleeve-like pattern. Venous drainage matters because it is often the overlooked half of spinal cord vascular anatomy, yet it underpins clinical entities such as spinal dural arteriovenous fistula and venous congestive myelopathy, where impaired outflow elevates intramedullary venous pressure and produces progressive lower extremity weakness and sensory change. For surgeons and interventionalists, tracing radiculomedullary inflow and radicular venous egress at the lumbar levels frames why embolization or ligation targets are selected and why inadvertent compromise of a dominant feeder such as the artery of Adamkiewicz can be catastrophic. Teaching the mirror-image logic of arterial supply and venous drainage pays dividends. It reduces “mystery” infarcts. Use this artwork in neuroanatomy and gross anatomy teaching to pair lumbar plexus organization with its accompanying vascular corridors, or in neurosurgery, neuroradiology, and pain medicine materials that discuss foraminal approaches, radiculopathy, and spinal cord ischemia. It also suits journal figures and patient-facing education on spinal vascular malformations when you need an uncluttered, clinically oriented map of cord vessels and lumbar nerve relationships.
