Vedclass · Answer

(A) During muscle contraction,the sliding filament theory explains that the thin filaments slide over the thick filaments. As a result,the $I$ band and the $H$ zone shorten and may eventually disappear. The length of the $A$ band remains constant because the thick filaments do not change in length. The diameter of the muscle fibre does not increase; in fact,the muscle fibre shortens and thickens slightly due to the sliding mechanism,but the statement that the diameter increases is considered false in the context of the sliding filament mechanism compared to the other specific structural changes.
