The size of the nervous system ranges from a few hundred cells in the simplest worms, to around 300 billion cells in African elephants. The central nervous system functions to send signals from one cell to others, or from one part of the body to others and to receive feedback. Malfunction of the nervous system can occur as a result of genetic defects, physical damage due to trauma or toxicity, infection or simply of ageing.
With the help of the neurons, the nervous system is able to control all the activities of the body by transmitting signals or messages from the brain to other parts of the body and vice versa. The nervous system has two components, the central nervous system and the peripheral nervous system. Together with these two components, other organs that are part of the system include ears, eyes, sensory organs of taste and smell, and sensory receptors located in muscles, skin, joints and other parts of the body.
