Quizplus · Accepted Answer

In a lever system, the fulcrum is the pivot point around which movement occurs. In the case of the elbow joint, when the upper limb straightens at the elbow, the joint acts as a fulcrum as it is the point around which the lever (the upper limb bone) moves. The force is the muscular effort required to move the lever, and the resistance is the weight or load being moved.
