Editing Microvillus (section)

Thousands of microvilli form a structure called the [[brush border]] that is found on the [[Apical membrane|apical surface]] of some [[epithelial cells]], such as the [[small intestines]]. (Microvilli should not be confused with [[intestinal villi]], which are made of many cells. Each of these cells has many microvilli.)
Microvilli are observed on the plasma surface of eggs, aiding in the anchoring of sperm cells that have penetrated the extracellular coat of egg cells. Clustering of elongated microtubules around a sperm allows for it to be drawn closer and held firmly so fusion can occur. They are large objects that increase surface area for absorption.

Microvilli are also of importance on the cell surface of [[white blood cells]], as they aid in the migration of white blood cells.
