Microvilli are tiny, finger-like projections found on the surface of certain cells, especially those lining the intestines and kidneys. Their primary function is to increase the surface area of cells, facilitating better absorption and secretion. By expanding the surface area, microvilli allow cells to absorb more nutrients and expel waste efficiently.
While “microvilli tumor” isn’t a widely recognized medical term, it can be interpreted as tumors involving cells that contain microvilli or exhibiting microvilli-like structures. Some cancers, particularly those arising from epithelial cells (cells that line surfaces in the body), may display microvilli as part of their cellular architecture. Understanding these tumors requires a look into specific cancer types where microvilli play a role.
Anatomy Related to Microvilli Tumors
1. Epithelial Cells:
