Detailed explanation-1: -Gastrin is a peptide hormone primarily responsible for enhancing gastric mucosal growth, gastric motility, and secretion of hydrochloric acid (HCl) into the stomach. It is present in G cells of the gastric antrum and duodenum.
Detailed explanation-2: -Gastrin is produced by G cells of the pyloric antral part of the stomach. Its main physiologic function is the control of gastric digestion through the regulation of acid secretion and gastric epithelial cell proliferation.
Detailed explanation-3: -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.
