Vedclass · Answer

(B) In a skeletal muscle fibre,the $A-$ band contains both actin and myosin filaments.However,in the central part of the $A-$ band,there is a region where the thin actin filaments do not overlap with the thick myosin filaments.This central region,which contains only thick myosin filaments,is known as the $H-$ zone.Therefore,the $H-$ zone represents the central gap between the actin filaments that extend into the $A-$ band.

The $H-$ zone in the skeletal muscle fibre is due to:
