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. So the contraction of the thin and thick filaments causes our dense bodies to move closer, which causes the shortening of intermediate filaments found throughout the entire cell. And since some of these filaments are connected to the membrane of the cell, what it ultimately causes is the contraction and the shrinking of the entire cell as a whole. So basically, it contracts in the following fashion.
