This system plays a very important role in the body functions. The brain is the massaging center of the nervous system. It is made up of cerebrum, cerebellum and the brain stem or the medulla. The cerebrum controls different parts of the body. The cerebellum controls motor functions and muscular activity, and regulates voluntary movements. The medulla is responsible for automatic functions and transmits the messages between the brain and the rest parts of the body. When stimulated, neurons transmit nerve impulses and send messages from the sense organs to the nervous system about the surrounding environment. For example, sensory neurons are responsible for physical stimuli. In terms of such diverse roles, it is obvious that the nervous system greatly helps control and maintain the normal functions of different parts of our body.
