PseudopodiaPseudopodia

Pseudopods or pseudopodia (singular: pseudopodium) (from the Greek word ψευδοπόδια, ψευδός "fake, false" + πόδια "feet") are temporary projections of eukaryotic cells. Cells that possess this faculty are generally referred to as amoeboids. Pseudopodia extend and contract by the reversible assembly of actin subunits into microfilaments. Filaments near the cell's end interact with myosin which causes contraction. The pseudopodium extends itself until the actin reassembles itself into a network. This is how amoebas move, as well as some cells found in animals, such as white blood cells.

First, the cell surface extends a membrane process, a lamellipodium. Actin polymerizes, and, at its leading edge, the cell forms filaments that subsequently will blend into one another to form networks. It is supposed that actin polymerization is at the origin of the force propelling the cell forwards.[citation needed] Pseudopodia (
