WebSep 23, 2024 · Myofilaments are threadlike structures that comprise the myofibril inside the muscle cell (or muscle fiber). There are two main types of myofilaments: (1) thin filaments and (2) thick filaments. In a skeletal muscle, the myofilaments are arranged in a repeating pattern of light and dark bands. WebMay 17, 2024 · Myofibrils are composed of thick and thin filaments. Thick filaments are composed of the protein myosin; thin filaments are composed of the protein actin. Troponin and tropomyosin are regulatory proteins affiliated with the thin filament. Muscle contraction is described by the sliding filament model of contraction.
