and is prevented in the absence of , which causes calcium to trigger contraction through a response with regulatory proteins.
and filaments of the fibrils glide into one another as a result of calcium diffusing in the cytoplasm, resulting in the of the complete muscle fiber. The SERCAs pump (Sarcoplasmic/endoplasmic reticulum calcium ATPase) actively pumps ions back into the sarcoplasmic reticulum when the action potential decays.

Most of the mutations have no effects whatsoever on the organisms but some can be dangerous.
