Microvilli
Microvilli are short (less than one micron), non-motile extensions of the apical plasma membrane. By light microscopy (left), collections of microvilli constitute a brush, or striated, border. In optimal sections, individual microvilli can be resolved with the light microscope; however, they are better appreciated by electron microscopy (right image). Microvilli greatly increase the absorptive surface area of a cell. Small intestine 1000x, 10,000x
