Question
cells found primarily in the 'antrum' region of the stomach that secrete gastrin - the most potent of the 3 major stimulants of gastric acid secretion
cells that secrete somatostatin when the pH of the stomach falls below 3.0 - which puts the 'brakes' on gastrin and, consequently, acid secretion in the stomach
cells that secrete intrinsic factor - which is essential for adequate vitamin B12 absorption in the ileum of the small intestine
cells that secrete histamine in response to gastrin or acetylcholine, which then acts in paracrine fashion to stimulate gastric acid production by the stomach's acid-secreting cell population
cells that secrete H+ using luminal H/K ATPase pumps; the hydrogen ions they secrete create an electrical gradient that pulls chloride ions into the lumen, thus creating the stomach's hydrochloric gastric acid
cells responsible for secretion of pepsinogen - the precursor that is cleavage-activated to produce pepsin - the endopeptidase enzyme that begins chemical modification of proteins in the stomach.
Chief cells
D cells
ECL cells
G cells
Parietal cells
cells found primarily in the 'antrum' region of the stomach that secrete gastrin - the most potent of the 3 major stimulants of gastric acid secretion
Explanation / Answer
1)Cells found primarily in the 'antrum' region of the stomach that secrete gastrin-the most potent of the three major stimulants of gastric acid secretion are - G' cells.
2)Cells that secrete somatostatin when the pH of the stamach falls below 3.0 which puts the break on gastrin and consequently acid secretion in the stomach are- 'D'-cells.
3)Cells that secrete intrinsic factor-which is essential for adequate vitamin B12 absorption in the ileum of small intestine are - Parietal cells.
4)Cells that secrete histamine in response to gastrin or acetylcholine, which then acts in paracrine fashion to stimulate gastric acid production by stomach's acid- secreting cell population are - ECL cells.
5) Cells that secrete H+ using luminal H/K ATP ase pumps ;the hydrogen ions they secrete create an electrical gradient that pulls chloride ion in to the lumen, thus creating the stomach's hydrochloric gadtric acid are- Parietal cells .
6)Cells responsible for production of pepsinogen - the precursor that is cleavage activated to produce pepsin-the endopeptidase enzyme that begins chemical modification of proteins in the stomach are - Chief cells
