Difference between Cilia and Microvilli

Cilia and microvilli are special types of protuberances from the surface some eukaryotic cells with specific functions such as movement, sensory functions or facilitating absorption.

Cilia (singular – Cilium) are narrow and long hair like protuberances from the apical surface of some epithelial cells. Cilia are made up of microtubules with a length of 5 to 10 µm and 0.2 µm in diameter.

Microvilli (singular – Microvillus) are microscopic cellular membrane protrusions that increase the surface area for absorption. Numerous microvilli together act as a structure called ‘Brush Borders’. The brush borders are abundantly present on the epithelial cells of the small intestine where they facilitate the absorption.
