Brunner’s glands

Mucus-secreting glands in the duodenum.

Glands in the duodenum and jejunum [Described 1687. After Johann Konrad Brunner (1653-1727), Swiss anatomist at Heidelberg, then at Strasbourg.]

Compound glands of the small intestine, found in the duodenum and the upper part of the jejunum. They are embedded in the submucosa and secrete mucus.

Compound glands of the duodenum end upper jejunum that are similar to the pyloric glands of the stomach. They are embedded in the submucosa and lined with columnar epithelium. They secrete alkaline mucus which neutralizes the hydrochloric acid entering the duodenum from the stomach.
