The uptake and release of calcium ions by the sarcotubular system are believed to be an integral part of excitation–contraction coupling and relaxation of muscle, and so it is important to ...

Since calcium is essential for muscle contraction and relaxation ... proteins from an extract of rabbit skeletal muscle sarcoplasmic reticulum, and when they measured the calcium binding activity ...

Skeletal muscle contraction is activated through voltage dependent release of Ca2+ from the intracellular storage location, the sarcoplasmic reticulum (SR) through ryanodine receptors (RyR). Ca2+ ...
