  1. 3Types of skeletons
    • Hydrostatic skeleton- Pressure
    • from internal body fluids support body (worm)

    • -Exoskeleton-hard, hollow
    • structure that covers the body (lobster)

    • -Endoskeleton- Hard internal
    • structures. (me)

  12. Sarcomere
    basic unit of myofibril Striated (striped) appearance with light and dark bands
  13. basic unit of myofibril Striated (striped) appearance with light and dark bands
    Sarcomere
  14. Sliding-filament model
    hypothesis that banding pattern in sarcomere are caused by thick and thin filaments rubbing sliding past one another in a contraction.

    long protein that makes up thick filaments.
  19. long protein that makes up thick filaments.
    Myosin
  20. Tropomyosin
    binds side of actin filament and blocks myosin binding (allows for relaxation)

  22. Troponin
    binds tropomyosin (allows for relaxation)
