Let's move on to our eyeband. The eyeband is this entire region that stretches not over a single sarcomere, but over two sarcommirs that are found adjacent to one another. So just like the h zone contains only thick filament, the iband only contains our thin filament. So it only contains these black regions, our thin filament, and it extends over two sarcommirs and not over a single sarcomere as our h zone does and the A band does. So now let's move on to our egg band. So the A band actually contains all of our thick filament.
