3. What is the major organs of your system and their jobs? The major organ of the nervous system are the brain and the spinal cord. The brain tells you what to do and how to react. Sciatic nerves send nerve impulses to the muscle and skin. The five sense’s are to see, to hear, to taste, to feel and to smell. Also every impulse is made of neutrons (nerve cells). The nervous system “talks to the other parts” of the body too.The major organ of the nervous system are the brain and the spinal cord. The brain tells you what to do and how to react.

4. There are 31 pairs of Spinal Nerves. They are mixed nerve that provide two way communications. Also an average brain weighs about 3 pounds. The spinal cord gets information to the brain(Spinal cord=highway of the body). Some other major organs of the brain are the hypothalamus, cerebellum, cerebrum, pituitary. The hypothalamus controls temperature, cerebellum controls how you move and balance, the cerebrum controls how you want to move and lastly the pituitary release hormones which controls growth.There are 31 pairs of Spinal Nerves.

5. What are the functions of the nervous system? How does it do it? The function are issuing nerve impulses and analyzing sensory data. Carrying the impulses to and from the body voluntary muscles can control and move your body. The nervous system transits signals through your body. The signals are transmitted by your brain.The function are issuing nerve impulses and analyzing sensory data.

6. The nervous system receives information and sends it to the brain. The brain is the main control of your body. It tells your body what to do.The nervous system receives information and sends it to the brain. The brain is the main control of your body. It tells your body what to do.

7. Why is your system important for survival? All the organ and muscles rely on these nerve impulses to function. It is the master control unit in the body. It has the blueprints of your body. The nervous system has the brain which you cannot live without it. The nervous system is what lets you feel things.All the organ and muscles rely on these nerve impulses to function.

8. The nervous system controls everything you do including breathing, walking, thinking and feeling. It controls an wide area of functions including some motor skills and body reactions.

9. Disease and disorders of the system? Alzheimer's disease- slowly over time destroys nerve cells and surrounds cells in center of nervous system.Alzheimer's disease- slowly over time destroys nerve cells and surrounds cells in center of nervous system. Schizophrenia- Change in behavior (actions)Schizophrenia- Change in behavior (actions) Multiple Sclerosis- Occurs when myelin is damaged.Multiple Sclerosis- Occurs when myelin is damaged. Autism- Trouble talking or showing communication like hand signal.Autism- Trouble talking or showing communication like hand signal.

10. Paralysis memory loss blindness, loss of motor skills, speaking ability, hearing loss, coma or transverse myelitis.
