- the thick cord of nerve tissue within the spinal canal, which in man gives rise to 31 pairs of spinal nerves, and together with the brain forms the central nervous system
- The thick, whitish cord of nerve tissue that extends from the medulla oblongata down through the spinal column and from which the spinal nerves branch off to various parts of the body.spinal marrow
- The long, cordlike part of the central nervous system that is enclosed within the vertebral column (spine) and descends from the base of the brain, with which it is continuous. The spinal cord branches to form the nerves that convey motor and sensory impulses to and from the tissues of the body.
The thick column of nerve tissue that extends from the base of the brain about two thirds of the way down the backbone. As part of the central nervous system, the spinal cord carries impulses back and forth between the brain and other parts of the body through a network of nerves that extend out from it like branches.
