Present, but not seen, are stem cells and endocrine cells. Circadian rhythm is the 24-hour internal clock in our brain that regulates cycles of alertness and sleepiness by responding to light changes in our environment. Secretes alkaline juices (which help maintain the correct pH) and mucus (for lubrication and protection). Brunner's glands (or duodenal glands) are compound tubular submucosal glands found in that portion of the duodenum which is above the hepatopancreatic sphincter (i.e sphincter of Oddi).It also contain submucosa which creates special glands. The mucus lubricates and sticks the food together. Unlike the esophagus, however, the duodenum has villi and intestinal glands in the lamina propria, like the rest of the small intestine (the submucosal glands of the duodenum are of secondary importance to the glands found in the lamina propria). Exocrine glands are glands that secrete substances onto an epithelial surface by way of a duct. 5. Brunner’s glands: These are branched tubular glands.

This gland secretes thin watery secretions, which are rich in enzymes and antibodies, and the ducts open onto surface of oral mucosa. The submucosa of the duodenum is the only site of the complex mucus-secreting duodenal glands (Brunner’s glands), which produce a bicarbonate-rich alkaline mucus that buffers the acidic chyme as it enters from the stomach. • Cells are mucous type.
