Several long, tubular gastric glands open in gastric pitso Gastric glands are divided into three groupsi) Pyloric glands :# In these glands mucus secreting cells predominate. These glands also contain neuroendocrine G cells (secreting gastrin) and cells which secret lysozyme. Parietal cells are few and chief cells are absent.ii) Cardiac glands :# These glands mainly contain mucus secreting cells. Chief and parietal cells are sparse.iii) Principal (main) glands :# These glands are found in body and fundus. These glands contain mainy chief (peptic or zymogen) cells and parietal (oxyntic) cells.
