The nervous system is a complex network of nerve cells (neurons) and supporting cells that transmit and process information through electrical and chemical signals. It allows the body to perceive, respond, and adapt to its environment, controlling movements, regulating bodily functions, and facilitating thought, emotion, and behavior.
