Cytoskeleton:

1. The cytoskeleton is a network of proteinaceous filaments known as cytoskeletal elements.
2. It is a framework that helps cells maintain the entire shape and internal organization of a cell.
3. It also helps in providing physical stability for cellular division and movement.
4. Common cytoskeletal elements are microtubules, intermediate filaments, and microfilaments.

Functions of the cytoskeleton:

1. Modifying cell shape.
2. They provide mechanical strength and integrity.
3. They help in permitting cell movement.
4. They also assist the intracellular transport of supramolecular structures, vesicles, and even organelles.
