Actin filaments enhance mechanical strength and assist in muscle contraction and cytokinesis. Intermediate filaments, such as keratins, provide structural stability. Microtubules, the largest fibers, aid in intracellular transport and chromosome movements during division, and form structures like cilia and flagella.
