"The human nervous system carries messages from one part of the body to another with speeds up to 265 miles per hour... When a person burns his finger with a match, the stimulus of burning is received on the skin of the hand by the sensory nerve. The sensation is registered in the sensory nerve cell; it is then transmitted to the motor nerve cell, which brings about movement of the muscles that control the hand. This causes the hand to release the match."
