Which are the most stable of cytoskeletal element?

The most stable of the cytoskeletal elements are microtubules and intermediate filaments. Microtubules provide structural support and are involved in intracellular transport and cell division, while intermediate filaments offer mechanical strength and resilience to cells. Unlike actin filaments, which are more dynamic and involved in cell motility, these elements maintain cell integrity and shape over longer periods. Intermediate filaments, in particular, are known for their durability and resistance to depolymerization.
