it’s important for the spinal cord to intercept messages of pain because the spinal cord is responsible for an automatic movement in response to a stimulus that’s called reflex, and make responding to the stimulus faster.example: putting your hand on a hot stove, 1. the receptors in your hand detect stimuli (hot temperature). they send messages through nerves to your spinal cord 2. responding nerves signals travel directly from the spinal cord to muscles in your arm, and you pull your hand away 3. AFTER you respond to the stimuli, nerve signals travel from the spinal cord to the brain, and you feel pain.
