2. What is the nervous system?
The nervous system is a complicated system of nerves and cells that send and receive messages to and from the brain and spinal cord to different parts of the body.
The are 2 sub-sections of the nervous system: Central nervous system(CNS) which mainly controls the body and mind and you also have the Peripheral nervous system (PNS) which consists of the nerves and ganglia outside of the brain.

3. Central Nervous System
The Central Nervous System controls most functions of the body and mind. It has 2 main pieces the brain and the spinal cord. The brain controls and interprets what our sensory organs give it to process.
The Spinal cord helps to allow for movement but it also helps deliver the messages to and from the brain.

4. The Peripheral Nervous system
The peripheral nervous system is the part that works mostly with the nerves and the ganglia on the outer edge of the brain and spinal cord. It is also the part of the nervous system that activates the fight or flight method.

5. Fight or Flight?
Also known as the hyperarousal, or the acute stress response works by activating the fight or flight method by sending electrical pulses through your nerves which either says hey this can be fought or RUN! If the decision takes too long you get a “deer in the headlights” affect

6. Organs In The System
The nervous system interacts with the brain, spinal cord, and sensory organs They are all connected by nerves to organs throughout the rest of the body The nervous system is responsible for control of the body and communication.

7. Overall functions of the organs
The brain controls motor functions, the body's ability to balance, interprets information.
The spinal cord connects a majority of the peripheral nervous system.
The sensory organs take in information to help the brain make decisions

8. Interaction with Muscular and respiratory Systems
The brain uses the nerves to tell the muscles when to move. The nerves also deliver information on what to do in a fight or flight case.
The brain sends pulses through the nerves to the lungs which tell them to move to collect and release oxygen and carbon dioxide. The brain also monitors blood gas levels.
