The cytoskeleton of a cell consists of three types of threadlike protein structures: intermediate filaments, microtubules, and microfilaments.

1. Intermediate Filaments: These are tough, rope-like protein assemblages that provide mechanical support for the cell. They are the most durable of the three types of filaments in the cytoskeleton and are not involved in cell movement.

2. Microtubules: These are hollow rods made of the protein tubulin. They function in cell division and serve as a "skeleton" that maintains cell shape. They also form the tracks along which organelles equipped with motor proteins move.

3. Microfilaments: These are thin, solid rods made of the protein actin. They function in muscle contraction, during cell division, and in cell motility. They also provide some rigidity and shape to the cell.
