Detailed explanation-1: -The central nervous system includes the brain and spinal cord. The peripheral nervous system includes the nerves that run throughout the whole body.
Detailed explanation-2: -Nervous tissue, present in both the CNS and PNS, contains two basic types of cells: neurons and glial cells.
Detailed explanation-3: -The CNS consists of the brain and spinal cord, while the PNS includes all other nervous system tissue. All sensory receptors, sensory neurons and motor neurons are part of the PNS. The bones of the skull and spinal vertebrae encase all CNS neurons.
Detailed explanation-4: -Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands. Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.
