So when the thin filament slides along our thick filament, let's say these two dense bodies, they move closer together, and that brings these dense bodies and all the other dense bodies also closer together. And notice some of these filaments are also attached to the membrane of the cell. So when we have the contraction taking place, this network of filaments basically contracts uniformly, and that causes the entire cell to basically shrink inwards and become smaller in size. So we have this contraction process taking place that is a result of this network of three types of filaments. So once again, there are three types of filaments. We have thin filaments, we have thick filaments, and we have intermediate filaments.
