  • sarcomeres make up myofibrils, which make up muscle fibers which make up fasiscles. As the smallest peices contract, everything contracts.
  • youre understanding this champ!!!
  • so the different layers of muscles are like russian nesting dolls?
  • well you see, the fasicles have endomysium which keeps all the fibers together, that is surrounded by perimysium and thats surrounded by epimysium
  • wait but how does all this stay together?
  • sometimes we just get sore, champ, just ice up!
