This system is composed of both sensory (afferent) neurons, which carry information from the nerves to the brain and spinal cord, and motor (efferent) neurons, which transmit information from the central nervous system to the muscle fibers.
It does this by extracting information from the environment using sensory receptors, sending signals that encode this information into the central nervous system, processing the information to determine an appropriate response, and sending output signals to muscles or glands to activate the response.
