Microvilli are finger-like projections present on the cell membrane, increasing cells’ surface area. It is mostly found in the small intestine, the surface of white blood cells, and egg cells. If we look at the structure of microvilli, each microvillus is formed by microfilaments which are held together by cross-linking of protein. Some bundling proteins like spin, violin, and fimbrin are involved in the cross-linking of this microfilament. Microvilli are smaller and narrower as compared to cilia. Their length is between 0.5 and 1.0 um, and their width is 0.1. The main function of the microvilli is to increase nutrient absorption in the small intestine. These also facilitate carbohydrate digestion. Microvilli present on the egg cell surface allow the anchoring of sperm cells with egg cells, and microvilli on white blood cells make them migrate
