The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement. According to the sliding filament theory, the myosin (thick filaments) of muscle fibers slide past the actin (thin filaments) during muscle contraction, while the two groups of filaments remain at relatively constant length.

WebThe head of each myosin molecule can potentially form a cross-bridge to a nearby thin filament. Which of the following is involved in the power stroke? The myosin head pivots at the head after it binds to actin, causing the thin filament to be pulled towards the center of the sarcomere.
