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.
The nervous system is responsible for transmitting and receiving electrical and chemical signals (messages) within the body. Each division of the nervous system plays a vital part in the functioning of the human body. The nervous system can also be considered the human bodyâs communication network. The nervous system sends messages through afferent neurons, efferent neurons and interneurons.
