Activation of muscle contraction could be a speedy event that's initiated by electrical activity within the surface membrane and transversal (T) tubules. This can be followed by unharness of metal from the inner membrane system, the sarcoplasmic reticulum.
Nervous stimulation causes a depolarization of the muscle membrane (sarcolemma) that triggers the discharge of calcium ions from the sarcoplasmic reticulum.
