Microvilli (singular: microvillus) are microscopic cellular membrane protrusions that increase the surface area of cells and minimize any increase in volume, and are involved in a wide variety of functions, including absorption, secretion, cellular adhesion, and mechanotransduction. Contents.housands of microvilli form a structure called the brush border that is found on the apical surface of some epithelial cells, such as the small intestines.
It has a surface area of over 200 meters. The internal walls of the small intestine are covered in finger-like tissue called villi. Each of these villi is covered in even smaller finger-like structures called microvilli. These villi and microvilli increase the surface area available for the absorption of nutrients. In the small intestine food that has already been broken down by chewing and stomach enzymes is further degraded by additional enzymes.
