A sheet-like protrusion lamellipodia and a rod-like protrusion filopodia are composed of actin cytoskeleton at the plasma membrane.
These tubes are called filopodia and they can bring messages back to the cell about both the chemical environment and the physical surroundings.
The morphogenetic movement of cells requires a positional cue from surrounding tissues to determine the direction of their movement by setting up the position of the migrating cells' filopodia or lamellipodia.
Other examples of the small GTPases are Rac and Cdc42, which participate in lamellipodia and filopodia formation, respectively.
