Duodenum
- Crypts of Lieberkuhn (Intestinal Glands)
(40x objective lens)
This high magnification
view of the duodenum shows the crypts of Lieberkuhn of the intestinal mucosa.
The crypts are lined by a simple columnar epithelium composed of absorptive
cells, goblet cells, and, in the bases of the glands, Paneth cells, which
often contain pink-stained (eosinophilic) granules. The glands are surrounded
by the highly cellular loose connective tissue of the lamina propria. At the
lower edge of the image is a portion of the muscularis mucosae, which separates
the mucosa from the underlying submucosa.
