Actin, myosin heads, myosin, myofilaments that do not lie in the H zone, the myofilaments that do not lie in I band, the filaments that attach to a Z disc.

Introduction:

The myofilaments are myofibril filaments made up of proteins mainly actin and myosin. These are present in the muscle fiber and are the key regulators of muscle contraction. These filaments are the contractile type of proteins which form groups that give the appearance of the repetitive bands to the cytoplasm.
