WebThick myofilaments are composed of a protein called MYOSIN. Each MYOSIN molecule has a tail which forms the core of the thick myofilament plus a head that projects out from the core of the filament. These MYOSIN heads are also commonly referred to as CROSS-BRIDGES. The MYOSIN HEAD has several important characteristics: WebOct 4, 2024 · Myofibrils are made up of two types of filaments: thin filaments and thick filaments.

WebThin filaments are a polymer of actin with tightly bound regulatory proteins troponin and tropomyosin ( Fig. 39.4 ). When the cytoplasmic Ca 2+ concentration is low, troponin and tropomyosin inhibit the actin-activated adenosine triphosphatase (ATPase) of myosin. Websmaller thin myofilaments are chiefly made of the protein actin. Let's discuss each myofilament in turn. Each actin molecule is composed of two strands of fibrous actin (F-actin) and a series of troponin and tropomyosin molecules.
