Microfilaments
Microfilaments also form the core of microvilli, which are short, finger-like, non-motile extensions from the apical surface of epithelial cells. The bundles of microfilaments create a stiff mechanical support for each microvillus, allowing them to project outward without bending or collapsing. These microfilaments are further anchored into a network of microfilaments, called the terminal web, located beneath the plasma membrane at the apex of the cells. Microfilaments are composed of actin protein and are often referred to as actin filaments. Small intestine 35,000x
