The Central Canal is a hollow tube that runs the length of the spinal cord. This passage is filled with cerebral spinal fluid, a colorless fluid that fills a space surrounding the complete central nervous system and various channels and chambers within the central nervous system. Cerebral spinal fluid protects the brain and spinal cord by serving as a cushion to absorb any physical shocks or sudden movements of the head.
