Related to Microfilaments: Intermediate filaments


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.

mi′cro·fil′a·men′tous (-mĕn′təs) adj.


(Biochemistry) thin filament, composed of the protein actin and associated proteins, that occurs abundantly in muscle and in the cytoplasm of other cells


(ˌmaɪ krəˈfɪl ə mənt)

a tubelike protein structure that is involved in cell movement and changes in cell shape.
mi•cro•fil•a•men•tous (ˌmaɪ kroʊˌfɪl əˈmɛn təs) adj.
