Pseudopods may be used for motility, or for ingesting nutrients or other particulate matter . Cells that make pseudopods are generally referred to as amoeboids . Pseudopods extend and contract by the reversible assembly of actin subunits into many microfilaments . Filaments near the cell's end interact with myosin which causes contraction . The pseudopod extends itself until the actin reassembles itself into a network . </P> <P> It is supposed that actin polymerization is at the origin of the force propelling the cell forward . Generally several pseudopodia arise from the surface of the body (polypodial, e.g. Amoeba proteus), or a single pseudopod may form on the surface of the body (monopodial, e.g. Entamoeba histolytica). </P>
