Sensory Input, Integration, and Motor output are the major functions of the nervous system.
- Your endocrine system works closely with your brain and central nervous system to control the creation of specific hormones and enzymes. Your digestive and excretory systems work with the nervous system in both conscious and unconscious ways. The nervous system sends signals to your brain to make your body alert that something is wrong. For example , if you fall on your knee , your nervous systems sends signals to your brain to let your body know that you've been hurt.
