What are the 3 functions of the central nervous system?
The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.
What are the 5 main parts of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.

How does the central nervous system affect behavior?
The central nervous system has a fundamental role in the control of behavior. It contains the brain and the spinal cord which are both encased in bone which shows their importance. Both the brain and spinal cord receive signals from the afferent neurons and send signals to muscles and glands through efferent neurons.

The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
