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. But both types of filaments give the cell structure, they give the cell the shape and increase the tensile strength of our cell. So basically, if we try to pull on the cell what keeps the cell from being split are these types of fibers the microfiliminants and our intermediate filaments. Now, let's move on to the thickest type of filament fiber known as the micro tubules.
