WebIn cardiac muscle cells, calcium is an important effector of the coupling between cardiac depolarization (excitation) and cardiac contraction (called “excitation-contraction coupling”). In these cells, the sarcoplasmic reticulum sequesters calcium ions and thereby maintains low calcium concentrations in the sarcoplasm.
