The cytoskeleton is composed of microtubules, microfilaments, and intermediate filaments

The cytoskeleton is a dynamic network of protein filaments found in the cytoplasm of eukaryotic cells. It is composed of microtubules, microfilaments, and intermediate filaments, which play important roles in maintaining cell shape, facilitating cell movement, and participating in cell division.

The microtubules are hollow tubes made of the protein tubulin and are involved in maintaining cell shape, cell division, and intracellular transport. Microfilaments, made of the protein actin, are involved in cell movement, muscle contraction, and cell division. Intermediate filaments provide mechanical strength to cells and are involved in maintaining cell shape and integrity.

Overall, the cytoskeleton plays a crucial role in providing structural support, facilitating cell movement, and participating in cell division. It is a dynamic and essential component of eukaryotic cells.
