- - - - myofilaments
        thick and thin protein filaments arranged in a specific order to create a sarcomere
    - - thick filaments
        composed of myosin molecules with a round head projecting out, the myosin head connects to the active site on the actin molecule when contraction occurs
      - thin filaments
        made of actin, troponin and tropomyosin
        
        actin
        compose the backbone of thin filament, has an active site that can interact with myosin
        
        troponin
        holds the tropomyosin in place until it is ready for contraction
        
        tropomyosin
        rope like, held in place by troponin, covers active site on actin
