What are the Crypts of lieberkuhn?

Answer 1

They are intestinal cells found in the Small Intestine (SI). They are in the inter-villi space (between villi) and project down into the lamina propria of the SI. They contain Paneth cells, which secrete lysozymes.

Answer 2

The Crypts of Lieberkühn, named after the anatomist Johann Nathanael Lieberkühn, are invaginations found in the lining of the small intestine. These crypts house stem cells that continuously replenish the epithelial cells of the intestinal lining. They also produce mucous that helps protect the intestinal wall from digestive enzymes.
