spinal cord - That part of the vertebrate central nervous system within the backbone. Consists of a hollow tube, but the hole is very small and the walls relatively and unevenly thick. Contains numerous nerve-cells and bundles of nerve fibres, particularly those connecting all levels of the spinal cord with the brain. Pairs of peripheral nerves, one nerve on each side per segment, leave the spinal cord to be distributed to the body. See also: Nerve Root. A great deal of simple co-ordination of movement of limbs, viscera, etc., is done in the spinal cord by reflexes.
