Quick Summary

Diagram showing the anatomy of the small intestine with labeled regions (duodenum, jejunum, ileum), a cross-section highlighting muscle and mucosa layers, an enlargement of mucosal folds (plicae circulares), and a detailed view of a villus structure with epithelial, goblet, endocrine, and Paneth cells, microvilli, blood capillaries, and lacteal.
structures of the small intestine The inner wall of the small intestine is covered by numerous folds of mucous membrane called plicae circulares. The surface of these folds contains tiny projections called villi and microvilli, which further increase the total area for absorption. Absorbed nutrients are moved into circulation by blood capillaries and lacteals, or lymph channels.

LieberkĆ¼hn's glands, also known as intestinal glands, are found at the base of the mucosal villi in the small intestine. These glands are crucial for digestion and absorption.1

Key facts about LieberkĆ¼hn's glands:
* Location: Situated at the base of the villi in the small intestine.1
* Cell Types: They contain undifferentiated cells for renewal and secretion, goblet cells that produce mucin, and endocrine cells. In the duodenum, they also receive secretions from Brunner's glands.1
* Paneth Cells: At the bottom of these glands are Paneth cells, which secrete protein-rich material and may have an antibacterial function.12
* Function: The cells lining these glands contribute to cell renewal and secretion, aiding in the digestive processes within the small intestine.1
