Amoeboid movement is a crawling-like type of movement accomplished by protrusion of cytoplasm of the cell involving the formation of pseudopodia. The cytoplasm slides and forms a pseudopodium in front to move the cell forward. This type of movement has been linked to changes in Action potential, the exact mechanism is still unknown. This type of movement is observed in amoeboids, slime molds and some protozoans, as well as some cells in man such as leukocytes. Sarcomas, or cancers arising from connective tissue cells, are particulary adept at amoeboid movement, thus leading to their high rate of metastasis.
