Identify the correct order used by the central and peripheral nervous systems to respond to stimuli. The central nervous system sends out the processed information to the peripheral nervous system. Receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment or from inside your body. The central nervous system processes information received from the peripheral nervous system. Information from receptors is sent to the spinal cord and brain by the peripheral nervous system. The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.
