How would you modify this experiment so that the mass lifted by the muscle contraction continues to increase for every trial? 2. A pin can be pressed against the skin lightly and elicit no response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc. Use what you know about threshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain).
