Myofibrils are made up of two types of filaments: thin filaments and thick filaments. Thin filaments are composed of strands of the protein actin and a regulatory protein coiled together, whereas thick filaments are composed of strands of the protein myosin. The thin and thick filaments form partially overlapping … See more A myofibril is a component of the animal skeletal muscle. Myofibrils are long filaments that run parallel to each other to form muscle (myo) … See more Myofibrils are made up of sarcomeres, the functional units of a muscle.
