What is the Nervous System?
The Nervous System consists of the Brain, Spinal Cord, Nerves, and Sense organs. Their functions are to receive and interpret sensory information, and in response, stimulate muscles, glands, and other organ systems. There are two major divisions of the nervous system; Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
There are 5 primary functions:
1. Sensory Input to the brain comes from receptors all over your body at both conscious and subconscious levels.
2. Motor Output from your brain stimulates the skeletal muscles to contract, enabling you to move. (The nervous system controls the production of sweat, saliva and digestive enzymes without active input from you).
3. Evaluation and Integration occur in your brain and spinal cord to process the sensory input and respond to it.
4. Homeostasis is maintained by your nervous system taking in internal sensory input and responding to it.
5. Mental Activity occurs in your brain so that you can think, feel, understand, respond, and remember.
