What constitutes the central and peripheral nervous systems? How are the components of central nervous system protected?
Central nervous system is composed of the brain and spinal cord. Peripheral nervous system is composed of nerves which are outside the spinal cord. Central nervous system has a well-developed system for protection. Brain is enclosed in skull for protection. Spinal cord is enclosed in vertebral column for protection. Additionally, the cerebrospinal fluid provides a cushion against mechanical shocks.
