Vedclass · Answer

(A) In a skeletal muscle fiber,the $A$-band contains both actin and myosin filaments. However,the central part of the thick filament (myosin) is not overlapped by thin filaments (actin). This central,lighter region within the $A$-band is known as the $H$-zone. Therefore,the $H$-zone represents the portion of the myosin filament that does not overlap with actin filaments.
