GENERAL HISTOLOGY

Detailed explanation-1: -The major cytoskeletal protein of most cells is actin, which polymerizes to form actin filaments-thin, flexible fibers approximately 7 nm in diameter and up to several micrometers in length (Figure 11.1).

Detailed explanation-2: -Microfilaments are part of the cytoskeleton that are composed of protein called actin. Two strands of actin intertwined together form a filamentous structure allowing for the movement of motor proteins.

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