WebThe relationship between the proteins and the regions of the sarcomere are as follows: Actin filaments, the thin filaments, are the major component of the I-band and extend into the A-band.; Myosin filaments, the thick filaments, are bipolar and extend throughout the A-band. They are cross-linked at the centre by the M-band. WebA. actin filaments become shorter when they combine with myosin heads B. myosin heads rotate when they attach to actin, causing the myosin filaments to fold in the middle C. thin myofilaments are pulled toward the center of the sarcomere by the pivoting of the myosin heads D.
