The cytoskeleton is an extensive network of long fibres and elements that provide shape, movement and anchorage for cells.Microtubules are the largest elements and are made from globular protein subunits called alpha-tubulin and beta-tubulin. These molecules join together in a tight spiral to form long hollow tubes and form a dense network throughout the cell.Microtubules give the cell its shape and stop the cell from collapsing because of their high compressive strength.They are also responsible for the transport of components around the cell such as the movement of chromosomes in mitosis.They provide tracks for the movement of vesicles around the cell and are the components of cilia and flagella that can move whole cells.
Microfilaments are contractile fibres made from the protein actin.Intermediate Filaments provide the cell with mechanical strength
