Microvilli are tiny, finger-like projections found on the surface of certain cells in the body, particularly in the intestines and kidneys. They play a crucial role in increasing the surface area for absorption and secretion. When microvilli are damaged or injured, it can lead to various health issues. This comprehensive guide will explore everything you need to know about microvilli injury, including anatomy, types, causes, symptoms, diagnostic tests, treatments, and prevention strategies
Microvilli are microscopic, finger-like extensions present on the surface of certain cells, especially in the small intestine, kidneys, and other absorptive cells. They significantly increase the surface area of cells, facilitating enhanced absorption and secretion processes. This increased surface area is vital for efficient nutrient uptake, waste removal, and various other cellular functions.
Anatomy of Microvilli
Microvilli consist of:
- Plasma Membrane: The outer layer that forms the structure of the microvilli.
- Actin Filaments: Structural proteins that provide rigidity and shape to the microvilli.
- Terminal Web: A network of actin filaments at the base of the microvilli that anchors them to the cell.
- Brush Border: A dense array of microvilli on the apical surface of epithelial cells, especially in the intestines.
