The central nervous system brain is the main part of the nervous system. The brain is protected inside the skull. The main function is to do the cranial activity. It is attached to the spinal cord and the spinal cavity.
The main work of the nervous system is to receive the message or signal from the other parts, organs and muscles and understand them. After receiving the message in the form of signal, it analyses the message and then act accordingly.
It`s act include sending message to the resulting organs. Once the analysis of the received message is done, what it does is it then generates the resultant signal and sends it via message to the parts required to act.
Let us take the example of ear. The ear is divided into two parts one external and the other internal both controlled by the central nervous system brain. The sound actually is collected by the external ear and then is send to the ear drum. The sound reaches the ear drum and vibrates there. Vibrations are converted to signals and sent to the brain. This is done by the inner ear. Receiving the signal, it acts accordingly.
The brain also helps us make the mater memorize and keep it in stored form. The central nervous system is not a volatile memory. It is divided into two parts: One the main memory and the second the subconscious memory. The subconscious mind stays awake all day and night. If it is affected it leads to many diseases. Normally the brain diseases can be cured by the physiatrists. What they normally do is they analyze the matter and act accordingly.
