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. Now, one important difference between microfilaments and intermediate filaments is intermediate filaments are also found in the nucleus of our cell. So intermediate filaments compose the nuclear lamina which is basically the fiber skeleton system found within our nucleus. So that's one major difference between microfilaments and our intermediate filaments.
