Calcium plays numerous roles in striated muscle, including excitation-contraction coupling and the stimulation of substrate oxidation by the mitochondria. These two topics are considered in this symposium. The purpose of this introductory paper is to present a conceptual framework about the control of calcium movements in striated muscle. Additionally, we provide a brief historical perspective regarding the key research observations leading to our current understanding of the various cellular systems controlling calcium flux in the muscle cell.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
