HUMAN NUTRITION

Detailed explanation-1: -The nervous system uses electrical and chemical means to help all parts of the body to communicate with each other. The brain and spinal cord make up the central nervous system. Nerves everywhere else in the body are part of the peripheral nervous system.

Detailed explanation-2: -The nervous system includes the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord, whereas the PNS is made up of the somatic and autonomic nervous systems.

Detailed explanation-3: -The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).
