Intermediate filament s are one component of the cytoskeleton-important structural components of living cells. Their size is intermediate between that of microfilament s and microtubules. They are assembled from several different proteins.
Microfilaments (or actin filaments) are the thinnest filaments of the cytoskeleton found in the cytoplasm of all eukaryotic cells. These linear polymers of actin subunits are flexible and relatively strong, resisting buckling by multi-piconewton compressive forces and filament fracture by nanonewton tensile forces.
