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). WebEach light region is divided in two by a dark band. The unit between two dark bands is known as a sarcomere.
