Diagram of a striated muscle (a) Group of muscle fibers make up a fascicle (b) A muscle fiber is made of thousands of myofibrils (c) Myofibrils contain dark (A) and light (I) bands and Z bands where actin originates from and moves towards the A band. (d) Myofibrils are made of repeating units known as sarcomeres. Sarcomeres contains thin actin filaments and thick myosin filaments.
