Nervous System

The central and peripheral nervous system provide sensory, integrative, and motor control throughout the body.

Central nervous system -CNS– brain and spinal cord

Peripheral nervous system – PNS – bundles of nerves that connect the central nervous system to cells outside the spinal cord.

Neurons – nerve cells. Neurons transmit information in the form of neurochemical changes called nerve impulses. Nerve impulses allow neurons to communicate with other neurons along with cells outside the nervous system.
