When you touch a hot pan accidently, you pull your hand back immediately. Identify the stimulus in the above statement.
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.
