WebMar 5, 2010 · The myofilaments include thick filaments, composed mainly of myosin, and thin filaments composed mainly of actin. The thick and thin filaments cause the cross-striations because of their regular overlap that is kept in register all across the diameter of the muscle fiber. The A-band corresponds to the thick filament.
