Effects of magnesium and calcium upon excitation-contraction coupling in the heart
Calcium (Ca2 ) availability to cardiac myofilaments is the primary factor determining the force of cardiac contraction. An intracellular organelle, the sarcoplasmic reticulum (SR), regulates the relaxation of the muscle as well as acting as a source of activating Ca2 during excitation-contraction co...
