A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) is a temporary arm-like projection of a eukaryotic cell membrane that is emerged in the direction of movement. Filled with cytoplasm, pseudopodia primarily consist of actin filaments and may also contain microtubules and intermediate filaments. Pseudopods are used for motility and ingestion. They are often found in amoebas. Different types of pseudopodia can be classified by their distinct appearances. Lamellipodia are broad and thin. Filopodia are slender, thread-like, and are supported largely by microfilaments. Lobopodia are bulbous and amoebic. Reticulopodia are complex structures bearing individual pseudopodia which form irregular nets. Axopodia are the phagocytosis type with long, thin pseudopods supported by complex microtubule arrays enveloped with cytoplasm; they respond rapidly to physical contact. Some pseudopodial cells are able to use multiple types of pseudopodia depending on

Las lamellipodias son amplias y delgadas. Las filopodias son delgadas, semejantes a filamentos, y se apoyan en gran medida por microfilamentos. Las lobopodias son bulbosas y amoebicas. Las reticulopodias son estructuras complejas que forman pseudopodias individuales que forman redes irregulares. Las axopodias son las phagagagocytosis con tipo, las thelopodias longinas son respaldadas por microtublas complejas envueltas
