What is a scaffolding of protein fibers that help a cell keep its shape?
microfilaments: microctubules and actin filaments
cytoskeleton? Microfilaments and microtubules? Like actin and myosin
In animal cells it is called cytoskeleton, a system of filaments found in the cytoplasm responsible for the maintenance of and changes in cell shape, cell locomotion, movement of various elements in the cytoplasm, integration of the major cytoplasmic organelles, cell division, chromosome organization and movement, and the adhesion of a cell to a surface or to other cells. Three major classes of filaments have been resolved on the basis of their diameter and cytoplasmic distribution: actin filaments (or microfilaments) each with an average diameter of 6 nanometers, microtubules with an average diameter of 25 nm, and intermediate filaments whose diameter of 10 nm is intermediate to that of the other two classes.
