Bio 252_Midterm Study GuideMuscular skeletal system as physics (page329-331) (synovial joints) -In producing movement, bones act as levers, and joints function as the fulcrums of these levers. A lever is a rigid structure that can move around a fixed point called a fulcrum, symbolized by. A lever is acted on at two different points by two different forces: the effort (E), which causes movement, and the load or resistance, which opposes movement.
