Microfilaments - Role of Cytoskeleton Structures
Microfilaments are as well present in all animal cells. They are found singly throughout the cytoplasm organized like a meshwork and measure 6 nm in diameter. Every microtubule is the polymers of the contractile protein actin. F actin or filamentous actin is the name provided to the assembled polymers of actin. The folding of cells brings about changes in the cell shape in the cytoplasm and the apical surfaces of cells become narrower. The narrowing of apical surfaces is brought about through contraction of microfilaments made up of actin.
