Detailed explanation-1: -If you touch something that is very hot, your hand moves away quickly before you even feel the pain. You don’t have to think about it because the response is a reflex that does not involve the brain. A reflex is a rapid, unlearned, involuntary (automatic) response to a stimulus (change in the environment).
Detailed explanation-2: -The muscular system and skeletal system work together closely to make movement possible. The human musculoskeletal system gives human the ability to move.
Detailed explanation-3: -Assertion: If your hands come in contact with hot objects (perhaps stove burner, hot plate, hot pan or a hot potato), a reflex causes you to immediately remove your hand before the message from the brain. Reason: Heat shock reflex arc is polysynaptic and the relay neuron also sends the information to the brain.
