Nervous system has 3 major functions:
1.Sensory input – sensory or afferent neutron detect internal or
external changes ( stimuli ) and send the message to the brain or
spinal cord.
2.Integration – interneurons in the brain or spinal cord process and
interpret the message from the sensory neurons, and relay the
massage back to body parts.

muscle or a gland).
