Facts about Cytoskeleton tell you about a complicated network of tubules and filaments that you can find in all cells of the living organisms. The cells are allowed to migrate because cytoskeleton system performs active contraction. Centrioles tend to be located near the nucleus when the cell isn't dividing. However, exceptions are always there. The cytoskeleton is the structural framework of cells, comprising three types of protein polymers. Of all of the filaments of the cytoskeleton, microfilaments are the thinnest. But did you know that we carry around 3 to 5 pounds of bacteria on our body.
