WebJun 16, 2024 · The cytoskeleton has three different types of protein elements. From narrowest to widest, they are the microfilaments (actin filaments), intermediate filaments, and microtubules. Microfilaments are often associated with myosin. They provide rigidity and shape to the cell and facilitate cellular movements. Webthe cell membrane in cross sections of muscle cells viewed after antibody staining (Pardo et al. 1983a,b). Longitudinal sections which just grazed the cell surface revealed riblike stripes of staining which they termed “costameres.” These costameres were located adjacent to the I band regions of the subsarcolemmal myofibrils (Figure 4).
