THE CENTRAL NERVOUS SYSTEM CONSTITUTES ONLY BRAIN AND SPINALCORD. AND PERIPHERAL NERVOUS SYSTEM INCLUDES ALL THE NERVES IN BODY.SO MOTOR NERVES AND SPINAL NERVES INVOLVE IN THIS PROCESS ARE CONSTITUENTS OF PNS.central nervous system is more protected as Its main line of defense is the bones of the skull and spinal column, which create a hard physical barrier to injury. A fluid-filled space below the bones, called the syrnix, provides shock absorbance. Unfortunately, this protection can be a double-edged sword. When an injury to the CNS occurs, the soft tissue of the brain and cord swells, causing pressure because of the confined space. The swelling makes the injury worse unless it is rapidly relieved. Fractured bones can lead to further damage and the possibility of infection.
