When you touch a hot object your hand automatically moves away from a object.Explain what causes this reaction?

The rapid withdrawal of your hand from a hot object is a reflex action controlled by the spinal cord, bypassing the brain for immediate response. When thermoreceptors in your skin detect high temperatures, they send signals to the spinal cord, which triggers a motor response to pull your hand away. This reflex occurs almost instantaneously to protect you from potential burns or injury, demonstrating the body's quick reaction to harmful stimuli.
