At least parietal cells) and chromogranin A (a marker of endocrine cells), indicating that  Lansoprazole is a specific inhibitor of the parietal cell proton pump. inhibits gastric acid secretion and therefore reduces the acid secretion of parietal cells. megaloblastic anemia, MCV >100 pernicious anemia can develop is by loss of gastric parietal cells which are responsible for the secretion of intrinsic factor,  Gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells  targeted mechanism of action. It is a specific inhibitor of the acid pump in the parietal cell. the acid pump and inhibits both basal and stimulated acid secretion.

2018-07-23 Abstract. The gastric parietal cell is a highly differentiated cell whose main and almost sole biological role is to secrete hydrochloric acid. In contrast to this narrow specialization, the functional regulation of the parietal cell involves a large span of physiological mediators of various chemical nature: ions (including H + itself), biogenic monoamines such as histamine and acetylcholine Parietal cells (also known as oxyntic or delomorphous cells), are the epithelial cells that secrete hydrochloric acid (HCl) and intrinsic factor.These cells are located in the gastric glands found in the lining of the fundus and in the body of the stomach.They contain an extensive secretory network (called canaliculi) from which the HCl is secreted by active transport into the stomach. 2021-02-06 Hydrochloric acid secretion by Parietal cells in stomach - Physiology AnimationsGastric acid, gastric juice or stomach acid, is a digestive fluid formed in The stomach mucosa’s epithelial lining consists only of surface mucus cells, which secrete a protective coat of alkaline mucus. A vast number of gastric pits dot the surface of the epithelium, giving it the appearance of a well-used pincushion, and mark the entry to each gastric gland, which secretes a complex digestive fluid referred to as gastric juice. 1) What are the secretions of the chief cells and parietal cells, and list the functions of each secretion. Chief cells: Secrete digestive enzymes including pepsin, is activated by stomach acid into pepsin, which is responsible for the stomachs ability to start the process to digest proteins.

The Correct Answer is. Cells found in gastric glands that secrete hydrochloric acid (for hydrolysis of ingested food) and gastric intrinsic factor (for absorption of vitamin B-12). Parietal (oxyntic) cells, large, spherical and eosinophilic, are responsible for the HCl production in the stomach and also secrete gastric intrinsic factor.

Gastrin, the major circulating stimulus of acid secretion, probably does not stimulate the parietal cells directly but acts to mobilize histamine from the ECL cells in the oxyntic mucosa.
