i tot is all cos without the bone the whole thing would not work

mathsparks' son: My answer is all. The bone is like the board for a lever, the joint is the fulcrum and the muscles are the effort. The dumbbell is the load. So all are needed. (Also, all the systems in the body work together so even the digestive and respiratory systems need to work too.)
