Quizplus · Accepted Answer

The correct sequence for muscle contraction begins with crossbridge formation between the myosin head and actin filament, followed by the power stroke where the myosin head pivots and pulls the actin filament towards the center of the sarcomere. Crossbridge dissociation occurs next, where the myosin head releases the actin filament, and finally, the cocking of the myosin head occurs, which resets the myosin head to its original position, ready to bind to another actin molecule and repeat the cycle.
