    What is the function of sarcomere?
    Sarcomere is the basic contractile unit of striated muscle containing actin and myosin proteins; hence, its main function is the regulation of muscle contraction. When a muscle fiber receives a signal for contraction, the myosin head binds with actin filaments forming a cross-bridge.

    What is sarcomere in skeletal muscle?
    The sarcomere is the main contractile unit of muscle fiber in the skeletal muscle. Each sarcomere is composed of protein filaments (myofilaments) that include mainly the thick filaments called myosin, and thin filaments called actin. The bundles of myofilaments are called myofibrils.

    What is the contraction action of a sarcomere?
    The basic contraction action of a sarcomere is a repeating cycle in which the myosin heads grab and crawl along the actin/tropomyosin filaments from one binding site to the next, pulling the Z-disks closer together (see Figure 10.3, and watch an animation).

    What is a sarcomere made up of?
    A sarcomere is a highly organized structure made up of thick and thin protein filaments; mainly of actin and myosin proteins. The thick filament is composed of the myosin protein, whereas, the thin filament is made up of the actin protein. Besides these two proteins, other proteins like troponin and tropomyosin are also present in a sarcomere.
