Stimulus and response: how we react to the world around us
WEBThe nerves in the peripheral nervous system often come in pairs, working in different directions. Sensory nerves take note of the stimuli (like the puddle you were trying to avoid when running) and deliver it to the brain. Motor nerves deliver the brain’s response to the muscles (like that in your legs) and glands.
