Only intermediate filaments play a purely structural role is the statement that accurately represents how intermediate filaments differ from actin filaments and microtubules.

The cytoskeleton is mainly made up of three types of elements of protein origin, intermediate filaments, actin and myosin filaments, and microtubules.

  • Intermediate filaments intervene in the cell ordering process, preserve the structural rigidity of the cell and keep the cell membrane stretched and prevent it from deforming under external pressures.

  • Microtubules together with actin filaments meet all cellular requirements for cell transport, maintenance of shape and movement.

Therefore, we can conclude that intermediate filaments have the main function of stiffening the structure of the cell, so they do not intervene in cell movement.
