Study Notes
- Cytoskeleton provides support, organization, and mechanical forces to the cell.
- It contributes to cell movement, division, and morphology.
- Microtubules are responsible for mitosis and cell division.
- Cytoskeleton is a polymer of polypeptides with dynamic changes.
- The majority of the dynamic changes occur at the ends of filaments.
- There are three types of filaments: actin microfilaments, microtubules, and intermediate filaments.
- Actin microfilaments are about 8nm, microtubules are about 25nm, and intermediate filaments are about 10nm.
- Cytoskeleton is essential for cell migration and contraction.
- It participates in the traffic of intracellular components.
- Cytoskeleton is necessary for the movement of flagella and cilia.
