Meaning and Definition
A microscopic, finger-like projection on the surface of certain cells that increases surface area for absorption.
In biology, microvilli (plural) collectively form a brush border on epithelial cells, such as those lining the small intestine, enhancing nutrient uptake. They are also found on other absorptive or sensory cells. The term can be used in extended, figurative contexts to describe any minute, densely-packed protrusion.

FAQ
Frequently Asked Questions
Microvilli are non-motile, actin-based projections that increase surface area. Cilia are motile, microtubule-based structures used for movement or sensory functions.
They are most densely packed on the apical surface of the epithelial cells lining the small intestine and the kidney's proximal convoluted tubule.
'Microvilli' is the plural form. The singular is 'microvillus', though it is less frequently used in isolation.
Yes. Conditions like coeliac disease can cause villous atrophy, damaging the microvilli and leading to severe malabsorption of nutrients.
