1.12 Simple columnar epithelium of the small intestine

Version française

Small portion of an intestinal villus lined with a simple columnar epithelium.

The cytoplasm of the epithelial cells (*) is long, slender and here slightly curved, with an elongated nucleus at its base. At the apexes of these cells, the acidophilic terminal bar-terminal web complex underlies the striated border which is composed of microvilli (arrowheads).

The epithelium is invaded by lymphocytes (arrows) coming from the subjacent connective tissue or lamina propria (LP).
