In turn this triggers the sarcoplasmic reticulum to release calcium ions into the muscle interior where they bind to troponin, thus causing tropomyosin to shift from the face of the actin filament to which myosin heads need to bind to produce contraction.
Calcium is the most abundant mineral in the body. Calcium's primary function is to build and maintain skeletal tissue. Ninety-nine percent of the body's calcium supply resides in the bone and teeth. Osteoblasts are bone-forming cells in which calcium phosphate is deposited. Ameleoblasts are the tooth- forming cells that deposit calcium to form teeth. Calcium has many other important functions in the body even though only 1% of the body's calcium performs these functions. Calcium is involved in maintaining the stability of fibrin, which allows blood to clot. Calcium is required for the transmission of nerve impulses.
