Z line: A protein disk within the I band that anchors the thin filaments and connects adjacent myofibrils. H zone: Located in the middle of each A band, this lighter stripe appears corresponding to the region between the thin filaments. • M line: Protein fibers that connect neighboring thick filaments.
