Central Nervous System

The vertebrate central nervous system consists of the brain and spinal cord. These lie in the midline of the body and are protected by the skull and vertebrae respectively. (see Nervous System)

The central nervous system along with the peripheral nervous system comprise a primary division of controls that command all physical activities of a vertebrate. Neurons of the central nervous system affect consciousness and mental activity while spinal extensions of central nervous system neuron pathways affect skeletal muscles and organs in the body.
