MICROANATOMY

Detailed explanation-1: -Measuring approximately 6 nm in diameter, microfilaments are the thinnest fibers of the cytoskeleton. They are polymers of actin subunits (globular actin, or G-actin), which as part of the fiber are referred to as filamentous actin, or F-actin.

Detailed explanation-2: -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-3: -Microfilaments. Microfilaments are thin (7 nm) molecules composed principally of actin protein subunits, which polymerize to form elongated actin filaments (F-actin).

Detailed explanation-4: -Actin filaments Also known as microfilaments, these are the smallest filaments (in diameter) in the cell, at about 7nm in diameter. They are made up of actin monomers which polymerise into filaments, that have two strands which wrap around each other. Actin filaments are important in cell shape and cell motility.
