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. WebThin myofilaments are 1 μm long and 8 nm in diameter, consisting primarily of actin. Actin is a globular protein with a molecular weight of 43 kDa. Two F-actin strands twisted in a double helix form the backbone of the thin myofilament and possess a complementary binding site for the myosin globular head. delta shower faucets sets complete
