Chief cells are part of fundic gland polyps (here shown in high magnification). [11]In gastric tissue, a loss of parietal cells due to chronic inflammation has been shown to affect chief cell differentiation and can induce chief cells to transdifferentiate back into neck cells and can lead to the formation of mucus cell metaplasia known as spasmolytic polypeptide expressing metaplasia (SPEM ...
When the stomach pH decreases (becomes more acidic), the ECLs stop releasing histamine. G cells – They secrete gastrin hormone. Gastrin stimulates the gastric glands to release gastric acid. These cells are mostly found in pyloric glands in the pyloric antrum; some are found in the duodenum and other tissues. The gastric pits of these glands ...
It is the cell responsible for secretion of chymosin (rennin) in ruminant animals and some other animals. [1] The cell stains basophilic upon H&E staining due to the large proportion of rough endoplasmic reticulum in its cytoplasm. Gastric chief cells are generally located deep in the mucosal layer of the stomach lining, in the fundus and body ...
A canaliculus is an adaptation found on gastric parietal cells. It is a deep infolding, or little channel, which serves to increase the surface area, e.g. for secretion. The parietal cell membrane is dynamic; the numbers of canaliculi rise and fall according to secretory n
Foveolar cells or surface mucous cells are mucus-producing cells which cover the inside of the stomach, protecting it from the corrosive nature of gastric acid. [1] [a] These cells line the gastric mucosa and the gastric pits. Mucous neck cells are found in the necks of the gastric glands.
Several types of endocrine cells are found in the gastric glands. The pyloric glands contain gastrin -producing cells ( G cells ); this hormone stimulates acid production from the parietal cells. Enterochromaffin-like cells (ECLs), found in the oxyntic glands release histamine , which also is a powerful stimulant of the acid secretion.
K cells: Intestinal glands: Secretion of the hormone glucose-dependent insulinotropic peptide, which stimulates the release of insulin M cells: Intestinal glands of duodenum and jejunum: Secretion of the hormone motilin, which accelerates gastric emptying, stimulates intestinal peristalsis, and stimulates the production of pepsin S cells ...
Gastric pits are indentations in the stomach which denote entrances to 3-5 tubular gastric glands. [ 1 ] [ 2 ] They are deeper in the pylorus than they are in the other parts of the stomach. The human stomach has several million of these pits which dot the surface of the lining epithelium .
