| Back | aka thin filaments, or microfilaments6-8nm diameter, made of fibrous protein actinflexible but resist deformation and transmit forces contribute to cell movement, interact with thick myosin filaments muscle cell contractionfound in microvilli, or just beneath PM, determine cell shape, contribute to cell locomotion, cytokinesis, and phagocytosis |
