Explanation:
Detailed explanation-1: -A reflex is a rapid automatic response to a stimulus. When you accidentally touch a hot object and automatically jerk your hand away, this is a reflex action.
Detailed explanation-2: -For example, if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. Luckily, this neurological relay race happens in an instant.
Detailed explanation-3: -What happens when you accidentally touch a hot plate? Sensors on your finger get activated and the information is relayed via nerves to your spinal cord (nervous system), which decides to immediately jerk back the hand by sending a signal to the arm muscles.
