WebSliding Filament Theory Explained. The sliding filament theory suggests that striated muscles contract through the overlapping of actin and myosin filaments, resulting in a shortening of the muscle fibre length.Cellular movement is controlled by actin (thin filaments) and myosin (thick filaments). In other words, for a skeletal muscle to contract, its … WebNov 3, 2024 · There are three layers of connective tissue that are found in the muscle.
