Transcript of Brain
The brain is one of the most important organs in the body. It is made up of 3 sections, the cerebrum, the cerebellum, and the brain stem.
The largest part of your brain is called the cerebrum. The cerebrum interprets input from the senses, controls movement, and carries out complex mental processes. The cerebrum is split into two parts, the right halve and the left halve. The right halve controls the left halve of the body and is usually associated creativity and artistic ability, while the left halve controls the right side of the body and is usually associated with mathematical skills and logical thinking.
The second largest part of your brain is the cerebellum. The cerebellum coordinates the actions of your muscles and helps you keep your balance.
The brain stem, which lies between the cerebellum and the spinal cord, controls involuntary actions. For example, neurons in the brain stem regulate your breathing and help control your heart beat.
Sight, smell, touch, hearing, and taste. These five things, are what we call the five senses, but they wouldn't mean anything if it wasn't for the nervous system. The nervous system connects the brain to the rest of your body by sending nerve impulses through the spinal cord and the peripheral nerves.
Krabbe's (krāb'ēz) Disease is a rare genetic disorder, that is currently incurable and is ultimately fatal. It is a genetic diseases that progressively destroys the white matter of the brain.
In Krabbe's disease, the enzyme galactocerebrosidase (GALC), which is essential for metabolizing several important compounds in the body, is deficient. Therefore, psychosine, a toxic substance which should be broken down and naturally released from the body starts to accumulate. This toxic build-up damages the central nervous system.
Even though 1 in 150 people carry Krabbe's Disease, it is not as widely known as some other Diseases such as Lou Gehrig's disease or Parkinson's disease. However it is just as, if not more than, important.
THE NERVOUS SYSTEM
This is what the brain looks like
Why is the Nervous System Important?
The nervous system is important to the body because with out it, we couldn't move, feel, or think. All of the organ systems are important, but they wouldn't function without the nervous system telling them what to do, nor would the nervous system work without some of the other systems helping it along. For example, the nervous system tells the muscular system how to move, while the respiratory system provides oxygen to help fuel the nervous system.

The Nervous System is Very Helpful
The nervous system helps all of the other body systems in some way or another. An example of this is how the nervous system helps the muscular system. The cerebrum and the cerebellum control movement while the spinal cord delivers messages to and from the brain.
Another example is the way the nervous system helps the digestive system. The medulla located inside the brain stem, controls involuntary movements such as digestion.
The nervous system needs help!
Even though the nervous system is a very helpful system, it still needs the help of the other organs. An example of this is the muscular system. The muscles provide protection for the nerves and also works with the nervous system to move the body.
