Calcium ions are vital for the contraction and relaxation of muscle cells as they are signaling molecules for muscle contraction. A nerve impulse initiates the release of calcium ions which liberates myosin attachment sites on actin filaments which induces contraction of muscles. The relaxation of muscles is gained when the calcium in the sarcoplasmic reticulum returns back.
