Cross bridge cycle vs sliding filament theory

WebSliding Filament Theoretical Explained. The slide filament theory suggests that striated muscles contract tested the lapping of actin the myosin filaments, resulting in a shortening of that string fibre length.Cell movement is controlled by actin (thin filaments) and myosin (thick filaments).
