The nervous system is a complex network of cells and tissues that coordinates and controls various bodily functions. It consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, while the PNS comprises nerves that connect the CNS to the rest of the body. This system is responsible for processing sensory information, controlling motor functions, and regulating various physiological processes.
