MICROANATOMY

Detailed explanation-1: -Microfilaments. Of the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest. They have a diameter of about 7 nm and are made up of many linked monomers of a protein called actin, combined in a structure that resembles a double helix.

Detailed explanation-2: -Microfilaments, also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton. They are primarily composed of polymers of actin, but are modified by and interact with numerous other proteins in the cell.

Detailed explanation-3: -The solid linear cytoskeletal elements having a diameter of 6nm and made up of a single type of monomer are known as microfilaments. They are ultramicroscopic long, narrow, cylindrical rods or protein filaments which occur in eukaryotic plant and animal cells.
