Understand the structure and functions of the central nervous system. A nervous system can be defined as an organized group of cells, called neurons, specialized for the conduction of an impulse—an excited state—from a sensory receptor through a nerve. The human peripheral nervous system consists of an elaborate network of sensory and motor nerves that convey information to and from the central nervous system—the brain and the.

Human nervous system, system that conducts stimuli from sensory receptors to the brain and spinal cord and conducts impulses back to other parts of the body. The nervous system forms an extremely complicated set of links between different parts of the body, and is divided into (a) the central nervous system, composed of (i) the brain, and (2). The human nervous system includes the brain and the spinal cord, which make up the central nervous system, and the nerves that run throughout the body, which make up the peripheral.
