What are the characteristics of the central nervous system?

Important neuroanatomical features of the CNS include neurons, glial cells, axons, membranes, and the neural tube and the ventricular system. The major subdivisions of the brain are the telencephalon, diencephalon, and brainstem. Additional components of the CNS include the cerebellum and spinal cord.

What are the 3 functions of the central nervous system?

The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.

What are the two main parts of the nervous system?
