spinal cord

Part of the central nervous system extending from the base of the skull through the vertebrae of the spinal column. It is continuous with the brain stem, and like the brain it is encased in a triple sheath of membranes. Thirty-one pairs of spinal nerves arise from the sides of the spinal cord. The spinal cord carries information from the body's nerves to the brain and signals from the brain to the body.
