Final answer:
When you touch a hot object with your hand, your brain sends signals to your muscles to quickly withdraw your hand. This reflex action helps protect your hand from getting burned.
Step-by-step explanation:
When you touch a hot object with your hand, the nerve endings in your skin detect the high temperature and send electrical signals to your brain. Your brain then processes these signals and sends a command to your muscles to quickly withdraw your hand from the hot object. This rapid response is a reflex and is designed to protect your hand from getting burned.
