Pseudopods or pseudopodia (false feet) are temporary projections of eukaryotic cells. Cells having this faculty are generally referred to as amoeboids.
First, the cell surface extends a membrane process, named lamellipodium. Polymerization of actin takes place and form filaments at the leading edge, which subsequently will blend into one another to form networks. We suppose that actin polymerization is at the origin of the force propelling the cell forwards.
They are involved in a variety of cell activities, most notably:.
