The spinal cord is a long, thin, cylindrical bundle of nerves that runs from the brainstem to the lower back. It is responsible for transmitting sensory information from the body to the brain, and motor commands from the brain to the body. 🧠💭💪 The spinal cord receives its blood supply from a network of arteries that provide oxygen and nutrients to the nerve tissue. 💉🩸

Several arteries supply the spinal cord, including the arteria vertebralis, arteria spinalis anterior, arteria spinalis posterior, arteria radicularis, arteria vasocorona, and arteria segmenti. Here is a brief explanation of each:

This artery arises from the subclavian artery and enters the spinal canal through the foramen magnum. It supplies blood to the cervical and upper thoracic portions of the spinal cord. 🩸💡
