The brain is the single most important part of the body. It is a very versatile organ that performs multiple functions and also very intricate functions. Each and every part of the brain is important and without brain function, the person is as good as dead. The brain is also the organ that controls all the various parts of the body and their activities. The brain controls the breathing, movements and also thinking.

In case of brain damage:

Any disease of the brain can make a person like a vegetable if it is severe. Brain injuries are common in road traffic accidents and it makes the person lose consciousness at times. When the injury is severe and the brain is completely dead, even though the person is breathing, there may be little or no chance of the person to have a life after that and this is the reason for the withdrawal of life support to brain dead patients.

Composition of the brain:

The brain is actually nervous tissue that is very highly specialized. It contains the various nerve cells for various functions. The brain contains the gray cells and the neurons that help the person to have good function. As the person gets older, the amount of neurons those lose their function increase. This is one of the important reasons because of which people lose a lot of their functions, as they get old. One of the most common examples of this is the occurrence of Alzheimer's disease in many old people and the incidence of the disease increases as the age increases.

Important functions of the brain:

1. Movements:

The brain is the control of the whole locomotor system. This means that the limbs including the hands and the legs are all completely under the control of the brain. When a person des not have proper brain function, the usual casualty is the, locomotor system. This is the problem commonly seen in stroke patient where a part of the brain stops functioning due to the blood clot and this in turn causes the one side of the body muscles to become paralyzed. Even in various other brain disorders like Parkinson's disease, the locomotor system is affected.

2. Thinking:

The thought process to is controlled by the brain. Whatever the person thinks can only be from the brain and the brain processes the information. There are various parts of the brain that control these thoughts.

3. Breathing:

Though the function of breathing is done by the lungs and associated parts of the body, the control of the breathing is by the brain. This is the reason for many people who have spinal cord injury have to be put on a ventilator. The person may have had damage to the part of the brain and the transmission of the breathing impulses are stopped. This makes it imperative that the person is on a ventilator.

4. Other functions:

There are various other functions that are also directly controlled by the brain. The brain also controls the memory that a person has. If a person is not having proper memory, then it can cause the person to lead a life that is not fulfilling. This is in fact dependant on the function of the brain.
