Cytoskeleton Structure Determines Function Kyndal Goodwin – B3
The cytoskeleton is made up of: • Actin filaments • (also called microfilaments) • - Intermediate filaments • Microtubules • Function: • - maintains cell shape • - protects the cell • - enables cellular motion • - plays an important role in intracellular transport • - is very important in cell division • aids movement of materials in and out of cells • aids muscle fiber contraction and locomotion
The cytoskeleton is a three-dimensional structure that fills the cytoplasm in eukaryotic and prokaryotic cells. Its structure acts as a muscle and skeleton, for movement and stability. The long fibers of the cytoskeleton are polymers of subunits.
