Microvilli are the tiny projections in the cell lining the villi. It increases the surface area of absorption thereby increasing absorption.
Microvilli on the surface of epithelial cells such as those lining the intestine increase the cell’s surface area and thus facilitate the absorption of ingested food and water molecules. Microvilli are also sometimes called the intestinal brush border.
The combination of circular folds, villi and microvilli helps absorption by increasing the surface area of the small intestine by 30 to 600 times.
<h3>
Where the Brush border of small intestine cells is formed ?</h3>
The innermost layer lining the lumen of the alimentary canal is the mucosa. This layer forms irregular folds (rugae) in the stomach and small finger-like folding called villi in the small intestine.
The cells lining the villi produce numerous microscopic projections called microvilli giving a brush border appearance found on the apical surface of some epithelial cells. These modifications increase the surface area enormously and help in secretion and absorption.
Microvilli are covered in the plasma membrane, which encloses cytoplasm and microfilaments. Though these are cellular extensions, there are little or no cellular organelles present in the microvilli. Hence, the brush border of small intestine cells is formed of microvilli.

The incest taboo is a universal rule, that is, it is present in all human societies for which there is an ethnographic record. It consists in prohibiting the occurrence of sexual and marital relations between close relatives, as occurs between parents and children and siblings. Its existence would not have resulted from genetic problems, as many imagine, but, above all, from socio-cultural issues, such as the need for social relations guided by reciprocity and alliance between families. If it were a prohibitive rule determined biologically, there would certainly be a taboo of incest among non-human primates, felines, canids, cattle, etc. Therefore, kinship is a relationship constructed socially and culturally, as it happens, just to exemplify, between parents and adopted children.
The recognition and classification of relatives varies from one society to another and there are the most complex rules on incest. An example of this is society the father's brother is called the uncle, the paternal uncle. In certain indigenous societies he is also considered a father and, therefore, his children are brothers (not cousins) of his brother's children. In such cases, the recognition of who is a brother implies knowing with which relatives it is forbidden to have sexual and marital relations. There is, however, the registration of marriage between brothers in ancient Egyptian royalty and among the Incas, among others, but they are exceptions to the rule.
