And this gives the cell the ability to resist tensile forces. So microfilaments give the cell tensile strength. So we see that not only are they responsible for our contraction of cells such as the muscle cells, they also stabilize the shape and structure of our cell and they give our cell ten style strength. Now, let's move on to the second type of fiber known as the intermediate filament. And these are known as intermediates because they're slightly greater in diameter than the smallest type of microfilin. So our diameter of intermediate filaments is about 10 nm.
