Spinal Cord Nerve Branches The anterior root is the motor (efferent) root that carries motor information to the body from the brain. The spinal nerve emerges from the spinal column through the opening (intervertebral foramen) between adjacent vertebrae.Click to see full answer. Then, where does the spinal cord run in relation to the vertebrae?Spinal cord. The spinal cord, about 45 cm in length, extends from the foramen magnum, where it is continuous with the medulla oblongata, to the level of the first or second lumbar vertebra (The range is T12 to L3). Below that level, the vertebral canal is occupied by spinal nerve roots and meninges.Furthermore, where does the spinal cord begin? In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and entering the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends. Correspondingly, what flows through the spinal cord? It flows through the ventricles and in spaces between the meninges. Cerebrospinal fluid also brings nutrients from the blood to the brain and removes waste products from the brain. The spinal cord is made up of bundles of nerve fibers. It runs down from the brain through a canal in the center of the bones of the spine.Is the spinal cord protected by the spine?The spinal cord is protected by bones, discs, ligaments, and muscles. The spine is made of 33 bones called vertebrae. The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Ligaments and muscles help keep the vertebrae in the right position.
