The Implication Of Women In The American Revolution - The Steps of Muscle Contraction: The Sliding Filament Theory Key events that must take place before the contraction of a muscle fiber begins: SR releases calcium ions into the cytosol The calcium ions will bind to troponin which causes the troponin-tropomyosin complexes to move away from the myosin binding sites on actin. Muscle - Muscle - The myofibril: Electron micrographs of thin sections of muscle fibres reveal groups of filaments oriented with their axes parallel to the length of the fibre. There are two sizes of filaments, thick and thin. Each array of filaments, called a myofibril, is shaped like a cylindrical column. Along the length of each myofibril alternate sets of thick and thin filaments overlap. The sliding filament theory explains the process of muscle contraction during which the thin filaments slide over the thick filaments, which shortens the myofibril. Each muscle fibre has an alternate light and dark band, which contains a special contractile protein, called actin and myosin respectively. A Thousand Splendid Suns Feminist Analysis
