Calcium (Ca) - Chemical properties, Health and

Calcium . The chemical element Calcium (Ca), atomic nuer 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium.A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns.

The Importance of Calcium in Muscle Contraction

The Calcium Cycle. Muscle contraction begins with an electrical "go" signal from your brain. The signal stimulates the SR to open its calcium gates, flooding the myofilaments with calcium. The sudden increase in calcium concentration sets off an energy-consuming chain reaction that causes the myofilaments to change shape and shorten.
