Cytoskeleton is tension bearing elements
WebSep 28, 2012 · The purpose of the present article is to consider the cytoskeleton as a discrete network of force-bearing elements, and present a structural mechanics based … WebCollectively, this network of protein fibers is known as the cytoskeleton. There are three types of fibers within the cytoskeleton: microfilaments, intermediate filaments, and microtubules ( Figure ). Here, we will examine each. Microfilaments thicken the cortex around the inner edge of a cell; like rubber bands, they resist tension.
