Cytoskeleton components, diagram. The cytoskeleton is the internal support structure of a cell, composed of filaments of various diameters in nanometres (nm). At left, the globular protein actin (orange) forms a microfilament (6nm). At centre, intermediate filaments (red, 10nm) are composed of a family of various proteins. The thickest of the filaments are the microtubules (green, right, 25nm), composed of the protein tubulin. Some of their roles in a cell are shown across bottom. From left to right cell contraction and movement; cell nucleus and desmosomes (cell-cell adhesions); and a mitotic spindle (below the nucleus).
