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.
