Dark a band function
WebThe A band is dark because of the thicker myosin filaments as well as overlap with the actin filaments. The H zone in the middle of the A band is a little lighter in color because it only contain the portion of the thick filaments that does not overlap with the thin filaments (i.e. the thin filaments do not extend into the H zone). WebThe word anisotropic band of a skeletal muscle fibre refers to its. Q. A.A-bands of the muscle is dark and contain myosin. B.I-bands are the light bands and contain actin. C.During muscle contraction the A-band contracts. D.The part between the two Z-lines is called as sarcomere. E.The central part of thin filament, not overlapped by thick ...
