There are three different types of myofilaments: thick, thin, and elastic filaments. Thick filaments consist primarily of the protein myosin. Each thick filament is approximately 15 nm in diameter, and each is made of several hundred molecules of myosin. A myosin molecule is shaped like a golf club, with a tail formed of two intertwined chains and a double globular head projecting from it at an angle.
Myosin head. Muscle contraction is caused by the sliding action of the thick filaments over the thin filaments of the myofibril. Myosin is a major component of thick filaments and exists as a hexamer of 2 heavy chains,[1] 2 alkali light chains, and 2 regulatory light chains.
