Primary Functions Of Your Nervous System

• Sensory Input: When you feel, see, hear, smell or taste, so basically your five senses, your nerves send signals to your brain.
• Integration: Then your brain processes these signals and interprets them. It decides what to do with these signals.
• Motor output: After deciding what to do it sends out a signal and reacts to the signal.

Example 1: Someone says your name, so you turn around and look for them.

Example 2: You feel an insect on your leg and then swat it off.
