Cell projectionPseudopodium

Definition

The pseudopodium is a thick knobby cell protrusion. Pseudopodia are produced by polymerization of extensive dendritic meshwork of actin filaments along broad sectors of the cell surface. These temporary irregular and dynamic protrusion or retractile processes of a cell, are associated with ameboid movement (crawling). Pseudopodium, or "false foot", mostly used for motile protozoans is comparable to the 'lamellipodium' in vertebrate cells.
