Intestinal microvilli. Coloured transmission electron micrograph (TEM) of an epithelial cell from the small intestine showing microvilli. This intestinal cell absorbs nutrients from digested food. To increase the surface area available for absorption from the gut lumen (yellow) each cell is covered in thousands of microvilli (pink). These long finger-like projections together constitute a "brush border". The core (dark pink) of each microvillus is composed of microfilaments. These filaments contain contractile proteins providing primitive motility to the microvilli. Below them is the cell cytoplasm (blue). Magnification unknown | |
