WebbBy the centre of contractile component, sarcomere, there is HYDROGEN zones. It is also toward one centre of dark band/A band. The H zone vanish when actin filaments sliders inside A belt during contraction of myofibril. () The illustration above is that of sarcomere. A is delimited to Z lines on send sides. There is dark A banding where myofilaments … WebbBe sure you can identify the borders of the muscle cell. You might see occasional nuclei which appear to be centrally located, but aren't. Why? Answer Peripheral position of the elongate nuclei just inside of the sarcolemma (plasma membrane). Note that each cell contains large numbers of nuclei.

WebbThe H zone—the central region of the A zone—contains only thick filaments (myosin) and is shortened during contraction. The H zone becomes smaller and smaller due to the increasing overlap of actin and myosin filaments, and the muscle shortens.
