The spinal cord blood flow is a remarkable vascular network that ensures continuous oxygen and nutrient supply to one of the body’s most critical neural pathways. The spinal cord receives its primary blood supply from the Anterior Spinal Artery and two Posterior Spinal Arteries. The anterior spinal artery runs along the front of the cord and supplies nearly two-thirds of its structure, while the posterior spinal arteries nourish the dorsal regions responsible for sensory processing. This intricate circulation supports the transmission of motor and sensory signals between the brain and the rest of the body.

Additional reinforcement comes from segmental vessels such as the Artery of Adamkiewicz, the largest radiculomedullary artery, which plays a crucial role in maintaining blood flow to the lower thoracic and lumbar spinal cord. These vessels form a dynamic vascular network that protects neural tissue from ischemia and maintains spinal cord function. Understanding this complex blood supply is essential in neurology, spinal surgery, and trauma care, as any disruption can lead to severe neurological deficits.
