Identify the structures labeled a, b, and c in the diagram of a sarcomere above.

A sarcomere is defined as the region of a myofibril contained between two cytoskeletal structures called Z-discs (also called Z-lines), and the striated appearance of skeletal muscle fibers is due to the arrangement of the thick and thin myofilaments within each sarcomere (Figure 10.2.2). A sarcomere is the functional unit of striated muscle. This means it is the most basic unit that makes up our skeletal muscle. Skeletal muscle is the muscle type that initiates all of our voluntary movement. Herein lies the sarcomere's main purpose. Sarcomeres are able to initiate large, sweeping movement by contracting in unison. A Fig. B Fig. QUESTIONS: 10. Label the thick and thin filaments in Figs. A, B, and C above 11.
