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. So these fibers are actually composed of several types of different proteins and are slightly thicker than the microfilaments that we discussed in this section here. Now, just like the microfilaments, these intermediate filaments also give the cell tensile strength. They increase the stability of the cell and give the cell its shape as well as its structure.
