I band, A-band, and how they vary with actin myosin overlap

[sundew773]

I have a question that asks the difference between the actin and myosin filament overlap/non-overlap in the I-band, A-band, and H-zone...and then asks how the force varies with the actin-myosin overlap.

In my notes, I find that (though please correct me if I'm wrongt:

A-band is thick and contains myosin and actin

I-band is thin and just contains actin

H-zone is an area in the center of the A-band that has only myosin.

So, how do the forces vary with actin-myosin overlap?

Any help is greatly appreciated
