It is crucial to the very process that enables the chambers of the heart to contract and relax, a process called excitation-contraction coupling. It is important to understand in quantitative detail exactly how calcium is moved around the various organelles of the myocyte in order to bring about excitation-contraction coupling if we are to understand the basic physiology of heart function. A Closer Look at Excitation-Contraction Coupling: Stimulation of a muscle fiber opens Na+ channels (= acetylcholine or ACh receptors) in the synaptic sarcolemma (= motor end-plate). An influx of Na+ (= positive) ions through the open channels depolarize the area, producing an end-plate potential (= EPP). Excitation–contraction (EC) coupling in striated (skeletal and cardiac) muscle physiology is a term broadly used to define the physiological process of transduction of Expression and regulation of excitation-contraction coupling proteins in aging skeletal muscle. Functional and structural decline of the neuromuscular system is a recognized cause of decreased strength, impaired performance of daily living activities, and loss of independence in the elderly. However, in mammals, including humans, age-related loss of strength is greater than loss of muscle mass ….
