Calcium ions are stored in the sarcoplasmic reticulum, which is a specialized type of endoplasmic reticulum found in muscle cells. When a muscle cell receives a signal to contract, the sarcoplasmic reticulum releases the stored calcium ions into the cytoplasm, where they bind to proteins called troponin and tropomyosin to initiate muscle contraction.
