myotubule

Example:Unlike myotubules, which are intermediate filaments, microfilaments in muscle cells are thinner and primarily composed of actin.

Definition:A thin filament composed of actin, found in the cytoplasm of eukaryotic cells, which is part of the cytoskeleton, providing support, stability, and enabling cellular movement.

Example:While microtubules form part of the cytoskeleton, myotubules, being intermediate filaments, do not have the same role in microtubule organization.

Definition:A tubular structure composed of protein subunits, which is a key component of the cytoskeleton, providing structural support and a means for intracellular transport in eukaryotic cells.
