Topic

Cytoskeleton Structure and function

Framing Question

How do the different components of the cytoskeleton support a variety of cell functions, such as cell shape, division, movement, sensing the environment, and cell-cell communication?

Learning Objectives

  • Compare the characteristics and functions of microfilaments, microtubules, and intermediate filaments.
  • Compare the structure and dynamic properties of microtubules versus actin and how these properties contribute to the different functions of these polymers in cells.
  • Explain how motor proteins harness energy to move along cytoskeletal tracks.
