This free course, Intracellular transport, explains the function of the cytoskeleton and its role in controlling transport of vesicles between different subcellular compartments.
After studying this course, you should be able to:
- define and use each of the terms printed in bold in the text
- describe the characteristics of different intracellular compartments with respect to their structure, location and composition within a mammalian cell
- describe the traffic pathways between the endoplasmic reticulum, the Golgi apparatus, the endosomal compartments, and the basolateral and apical regions of the plasma membrane
- give examples of regulated and unregulated secretion, the mechanisms controlling the processes, and their functional significance
- give examples of endocytosis, the mechanisms involved and their functional significance.

The cytoskeleton is of fundamental importance to a cell, and the development of different elements of the cytoskeleton were key steps in the evolution of eukaryotic cells. The cytoskeleton controls cell shape and allows cell movement; it is required for many aspects of intracellular trafficking of vesicles and organelles, and it is involved in cell division. Because of its important role in facilitating the movement of vesicles between compartments, but a basic understanding of how the cytoskeleton works is equally important for cell division and cell migration.
