The arm straightens through the coordinated action of muscles and joints. When the biceps muscle relaxes, the triceps muscle contracts, pulling the forearm back and extending the elbow joint. This movement is facilitated by the skeletal system, where bones act as levers and joints serve as pivot points. The nervous system also plays a crucial role by sending signals to the muscles to initiate and control the movement.
