microfilament

(mī′krō-fĭl′ə-mənt)
n.
Any of the actin-containing filaments that are found in the cytoplasm of eukaryotic cells and are involved in generating cell movement, providing structural support, and organizing internal cell components. Microfilaments, along with intermediate filaments and microtubules, make up a cell's cytoskeleton.

microfilament

a fine, subcellular structure about 5–8 nm in diameter, composed of ACTIN or a similar protein and found in the cytoplasm of EUKARYOTE cells. Microfilaments are able to contract and are also involved in CYTOPLASMIC STREAMING and PHAGOCYTOSIS.
