Describe the major aspects of the cytoskeleton
What will be an ideal response?
The cytoskeleton is composed of microtubules, microfilaments, and intermediate filaments. Microtubules serve a variety of functions including maintaining the shape of cells, coordinating complex intracellular movements, and serving as the main structural component of cilia and flagella. Microfilaments play a major role in cellular contractile systems, including muscle contraction. Intermediate filaments resist mechanical stress placed on cells.
