  7. Ca2+ Ca2+ Ca2+ Ca2+ Calcium ions are released from the sarcolemma after stimulation from the T system

  8. Ca2+ Ca2+ Ca2+ Ca2+

  9. Ca2+ Ca2+ Ca2+ Ca2+ the calcium ions bind to the troponin and changes its shape

  10. Ca2+ Ca2+ Ca2+ Ca2+ the calcium ions bind to the troponin and changes its shape

  12. Ca2+ Ca2+ Ca2+ Ca2+

  13. Ca2+ Ca2+ Ca2+ Ca2+ the troponin displaces the tropomyosin and exposes the myosin binding sites

  14. Ca2+ Ca2+ Ca2+ Ca2+

  15. Ca2+ Ca2+ Ca2+ Ca2+

  16. Ca2+ Ca2+ Ca2+ Ca2+ the bulbous heads of the myosin attach to the binding sites on the actin filaments

  17. Ca2+ Ca2+ Ca2+ Ca2+

  18. Ca2+ Ca2+ Ca2+ Ca2+

  19. Ca2+ Ca2+ Ca2+ Ca2+ the myosin heads change position to achieve a lower energy state and slide the actin filaments past the stationary myosin
