Answer 2

Answer:

When we touch any hot object we immediately withdraw our hands, this is due to phenomenon known as reflex action. In reflex action, sensory nerve endings present in our skin detect the heat and transfer the signal to the spinal cord. The spinal cord then coordinates the response and causes the muscles to move.
