amoeboid movement

Amoeboid movement is one example of how the microfilaments (the cell’s muscles) function. It is the same kind of movement that is involved in phagocytosis or “cell eating” which is the subject of my post last Nov. 19.

Biology – Online dictionary defines it as “A crawling-like type of movement in which the cell forms temporary cytoplasmic projections called pseudopodia (false feet) towards the front of the cell”.

Aside from the Amoeba, other cells that exhibit amoeboid movement are: neutrophils and macrophages (our professional phagocytes, remember?), monocytes (another kind of white blood cell), Kupffer cell of the liver, as well as cancer cells. Yes, cancer cells. This is the way by which cancer cells metastasize or spread to other parts of the body.
