The A-band contains primary myofilaments known as myosin filaments. There are three different types of myofilaments: thick, thin, and elastic filaments. • Thick filaments consist primarily of a type of myosin, a motor protein – myosin II. 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 p…
