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.
The filament shortens when stimulated, and the stalk coils like a spring. Earlier, the filament was called 'myoneme' (muscular filament), before it had been discovered that the chemical system that administers the contraction of the spasmoneme is different from the system used by a true muscular fiber.orticella are sessile (permanently attached to a substrate) organisms. However, young ones can be seen free-swimming. Adults also swim freely if their stalks are cut, or if they have to detach themselves from the substrate due to unfavorable conditions.
