The nervous system, often known as the neural system, is a sophisticated network of neurons dedicated to the transmission of messages. As we progress up the food chain, the neurological system becomes more sophisticated.
The nervous system's most basic job is to govern the organism's movement and to influence the environment (e.g., through pheromones). This is accomplished by transmitting signals from one cell to another, or from one body component to another. Signals that travel to muscle cells cause muscles to contract, and signals that travel to endocrine cells cause hormones to be released into the circulation or other internal fluids to cause the nervous system's output.
