The neurological system, also known as the nervous system, is a complex network that coordinates actions and reactions in the body. It consists of the brain, spinal cord, and nerves, which work together to transmit signals throughout the body. This system is responsible for processing sensory information, controlling movements, and regulating bodily functions. The neurological system is divided into 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 connects the CNS to the rest of the body. Together, they enable communication between different body parts and help maintain homeostasis.
