The cytoskeleton is located in the cytoplasm.

Spans cytoplasm and interconnects the nucleus in the extracellular matrix.**

•Supports cell and provides shape•Aids movement of material in and out of cell.•Supports the plasma membrane•Divides the cell in mitosis •Anchors organelles

•Microfilament (of actin)**

•Microtubules (of tubulin)**

•Intermediate Filament System**

1. 1. What are all of the fibers of the cytoskeleton made of?

2. What is the function of the many actin-binding proteins found in the cell?3. You have a long assembly of a single globular protein which is several hundred nm long and 7 nm wide. What do you have?
