“Brain has a small size relative to the body but its proper functioning is vital for life. The most important function of brain is coordination of body functions. For this purpose, brain has hundreds of millions of nerve cells. Nerves are cells of nervous system that transmit signals between brain and the body. Spinal cord is present in the middle. Every message being received or sent, passes through spinal cord. Brain is a delicate organ and it is protected by skull. If brain suffers from any disorder or trauma, it shows different signs. These signs depend on the part of the brain affected. Most common signs of brain disease include mental dullness, seizures, lack of coordination and behavioral changes.”
