I believe that the contraction of skeletal muscles is based on myosin cross bridges binding to actin the n flexing. Skeletal muscles consists of a repeating structure of myosin and actin fibers. Each myosin thick filament is surrounded by actin filaments, and each thin filament is surrounded by thick filaments. Several of these filaments bundles makes up the functional portion of a muscle cell.
