Sarcomeres are the active units of contraction in the [[Muskel/en|muscle]][[Zelle/en|cell]]. They consist of small strands of [[Aktinfilamente/en|actin]]- and [[Myosinfilamente/en|myosin filaments]]n and are activated by [[Calcium/en|calcium]] and [[ATP/en|ATP]]. The actin filaments push themselves into the sarcomere. The continuous action shortens the muscle. | Sarcomeres are the active units of contraction in the [[Muskel/en|muscle]][[Zelle/en|cell]].
