G cell - wikipedia G cell G cell Control of stomach acid Details System Digestive system Location Stomach and duodenum Function Gastrin secretion Identifiers Latin endocrinocytus G TH H3. 04.02. 0.00031 Anatomical terms of microanatomy ( edit on Wikidata ) In anatomy, the G cell ( or γ - cell ) is a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells. G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas and duodenum. The vagus nerve innervates the G cells. Gastrin - releasing peptide is released by the post-ganglionic fibers of the vagus nerve onto G cells during parasympathetic stimulation. The peptide hormone bombesin also stimulates gastrin from G cells. Gastrin - releasing peptide, as well as the presence of amino acids in the stomach, stimulates the release of gastrin from the G cells. Gastrin stimulates enterochromaffin - like cells to secrete histamine. Gastrin also targets parietal cells by increasing the amount of histamine and the direct stimulation by gastrin, causing the parietal cells to increase HCl secretion in the stomach.

G cells have a distinctive microscopic appearance that allows one to separate them from other cells in the gastric antrum ; their nuclei are centrally located in the cell. They are found in the middle portion of the gastric glands.
