intermediate filament

n.
Any of a group of protein filaments that are a component of the cytoskeleton in animal cells, are composed of a variety of proteins such as lamins and keratins, and provide structural support for the cytoplasm and nucleus. Intermediate filaments are intermediate in diameter between microfilaments and microtubules, the other components of the cytoskeleton.
