This is activated into pepsin by HCl. The mucous neck cell is found on the upper portion of gastric gland in the stomach. These secrete acidic and thin mucus. This triggers G cells to release gastrin, which in turn stimulates parietal cells to secrete gastric acid. Digestion - Wikipedia The next binding protein for B 12 is intrinsic factor (IF), a protein synthesized by gastric parietal cells that is secreted in response to histamine, gastrin and pentagastrin, as well as the presence of food.

Parietalceller, gastriska Svensk MeSH

Nuclei are spherical and centrally located. Cytoplasm is finely granular due to an abundance of mitochondria. Parietal cells secrete the hydrochloric acid of gastric juice and the antipernicious anemia factor. Parietal cells secrete hydrochloric acid (HCl), which maintains acidic pH of stomach and denatures proteins Chief cells secrete pepsinogen, which breaks down proteins when activated to pepsin by the acidic environment Microenvironment of the stomach is largely regulated by enteroendocrine cell hormone secretion and vagus nerve innervation The parietal cells secrete hydrochloric acid (HCl), which lowers the pH of the gastric juice (water + enzymes + acid).

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.

SUMMARY OF THE PRODUCT CHARACTERISTICS 1 NAME

These cells secrete pepsinogen (an inactive proenzyme form of pepsin). This is activated into pepsin by HCl. The mucous neck cell is found on the upper portion of gastric gland in the stomach.
