Explanation The spinal cord is an extension of the central nervous system; it contains the brain and spinal cord. The spinal cord begins at the occipital bone, passing through the foramen magnum and it enters the spinal canal at the beginning of the vertebrae. The spinal cord ends between the first and second lumbar vertebrae. The point at which spinal cord ends is called conus medullaris...
