WebMyofibrils are fibrous and long structures, and are made of two types of protein filaments that are stacked one on top of the other. Myosin and actin Myosin is a thick fiber with a globular head, and actin is a thinner filament that interacts with myosin during the process of muscle contraction. Myofilaments are the three protein filaments of myofibrils in muscle cells. The main proteins involved are myosin, actin, and titin. Myosin and actin are the contractile proteins and titin is an elastic protein. The myofilaments act together in muscle contraction, and in order of size are a thick one of mostly myosin, … See more 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.
