Pulling the hand back immediately after touching a hot object and feeling pain later demonstrates what?
Answer and explanation
Correct answer: The spinal cord produces a rapid response, while the brain provides conscious sensation
Touching a hot object activates pain receptors in the skin. The sensory impulse reaches the spinal cord, which quickly sends a motor command to withdraw the hand; this is a reflex action that reduces injury. At the same time, the impulse also travels to the brain, where pain is consciously perceived, often slightly later. Therefore A is correct, while B, C and D contradict the reflex pathway.
