When a person's hand touches a very hot object, a reflex arc is activated, which causes the person to quickly withdraw the hand. What is the correct sequence of events that occurs in this reflex arc
1. The hot object stimulates pain receptors in the skin of the hand.
2. Sensory neurons carry the pain signal to the spinal cord.
3. Interneurons in the spinal cord quickly process the signal and send a response through motor neurons.
4. Motor neurons carry the response signal to the muscles in the hand.
5. The muscles contract and the hand is quickly withdrawn from the hot object.
