The cross bridge cycle starts when myosin attaches to actin in a muscle cell. The process involves the initial loading of myosin with potential energy, allowing it to bind to actin. Once myosin binds, potential energy is released and the myosin's head shape changes, causing the filament to be pulled to the sacromere. This is known as the working stroke in muscular contraction.
