Arrаnge the steps оf muscle fiber cоntrаctiоn in the correct order:The muscle impulse reаches the sarcoplasmic reticulum and calcium is released.Thin filaments are pulled over the thick filaments.Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.The impulse arrives at the synapse and travels through the transverse tubules.The muscle fiber shortens and contracts.Myosin heads bind to exposed active sites on actin, forming cross-bridges.
