"WitrynaThese calcium ions are important for the contraction of the muscles. This influx of calcium ions is not seen in the case of skeletal muscles. When the cardiac myocytes are depolarized, the calcium channels in the sarcoplasmic reticulum are also kept open. Thus, the concentration of calcium ions greatly increases inside the cardiac myocytes. " - Importance of muscular contraction
