Microvilli are tiny, finger-like projections found on the surface of certain cells, particularly in the intestines. They play a crucial role in absorbing nutrients from the food we eat. When microvilli are damaged or not functioning correctly, it can lead to various health issues. This guide provides an in-depth look into microvilli diseases, covering their anatomy, types, causes, symptoms, diagnostic tests, treatments, and more. Whether you’re a student, patient, or healthcare professional, this article offers valuable insights in simple, easy-to-understand language.
Microvilli are microscopic, finger-like extensions of the cell membrane. They increase the surface area of cells, allowing for more efficient absorption and secretion. You can find microvilli in various parts of the body, including:
- Intestines: Aid in nutrient absorption.
