    increase in intracellular calcium led to skeletal contractions. However it was not until the early 1960s when the way calcium ions were stored in cells became clearer thanks to work from Ebashi and Lipmann. (Burgoyne and Petersen‚ 1997). Calcium signalling determines whether or not a cell is activated. It is determined by calcium-ON and calcium-OFF mechanisms. Calcium-ON is responsible for pouring Ca2+ into the cytoplasm‚ from both internal and external sources. The calcium-OFF mechanism however removes

    Describe the role of calcium in muscle contraction‚ where it is stored‚ and how it is released and recycled. Calcium storage‚ release‚ and recycling Muscles need to be malleable or have plasticity in order to function correctly. This is where calcium comes into the picture. All muscles use calcium molecules for regulatory and signaling purposes. Contraction control and relaxation control by calcium is achieved first by the activation of troponin-tropomyosin with the actin filaments. The second
