The cytoskeleton is a network of protein filaments that provides structural support, facilitates cell movement, and aids in intracellular transport. It comprises three main types of filaments:
1. Microfilaments (Actin Filaments): They are involved in maintaining cell shape, enabling cell motility, and playing a role in cytokinesis. 2. Intermediate Filaments: These provide mechanical support to the cell and help maintain its integrity. 3. Microtubules: They form the mitotic spindle during cell division, serve as tracks for intracellular transport, and contribute to the structure of cilia and flagella.
