Functions Of The Nervous System

Have you ever tried to swat down a fly? If you have, the thing that gives you that impulse is the Nervous System. The Nervous System functions with of your whole body. The brain sends //and// receives impulses caused by stimuli, changes in the environment. Then impulses travel through your nerves, which are positioned in the brain and spinal chord. The nerves take the impulses to parts of the body to make them move. The Nervous System functions in many ways and there are many different parts that work together to help you move, eat, breathe and live.

Organs That Make Up The Nervous System

There are quite a few organs that make up the Nervous System. [|The brain] is the control center of the system. There are 43 pairs of nerves in the body, 12 of those pairs are in the brain. The heart and the lungs don’t make the Nervous System work (contrary to popular belief) it’s the other way around. The heartbeat and breathing of a human being are controlled by the Nervous System. There are so many organs that form the Nervous System and each and every one play an important role in our survival.

Other Systems The Nervous System Works With

The Nervous System works with many other systems to help the body function. The Nervous System works with the [|Endocrine System] to dispense hormones properly and regulate growth. Another system that is related to the Nervous System is the [|Excretory System]. The Nervous System makes the heart pump out blood and the blood goes to the kidneys where it is filtered. The Skeletal and Nervous Systems are closely linked. The bones are moved by muscles, which are moved by nerves. The [|Digestive System] works with the Nervous System to help the body obtain nutrition. The brain gets signals about when the stomach is empty or full in order to be able to get the proper nutrition. The Nervous System is not alone; it would not function if it were. Like us the Nervous System needs to collaborate for survival. Diseases of The Nervous System and How To Prevent Them

The Nervous System is very important and we need to keep it safe and healthy. One injury that can be caused to the Nervous System is a concussion, which is a bruise in the brain. A disease the can happen is Alzheimer’s; this is a progressing deterioration of mental health (memory loss) usually found in older people. To prevent these things form happening we need to exercise mentally and physically. If we happen to exercise too vigorously we could cause injuries to the spinal chord. Injuries caused to the spinal chord can cause permanent paralysis (the lack of ability to move parts of the body or all of the body). To avoid injuries and diseases of the Nervous System we need to mentally and physically stimulate our body.
