<P> The pyloric glands are located in the antrum of the pylorus . They secrete gastrin produced by their G cells . </P> <P> There are millions of gastric pits in the gastric mucosa and their necessary narrowness determines the tubular form of the gastric gland . More than one tube allows for the accommodation of more than one cell type . The form of each gastric gland is similar; they are all said to have a neck region that is closest to the pit entrance and basal regions on the lower parts of the tubes . The epithelium from the gastric mucosa travels into the pit and at the neck the epithelial cells change to short columnar granular cells . These cells almost fill the tube and the remaining lumen is continued as a very fine channel . </P> <P> Cells found in the gastric glands include foveolar cells, chief cells, parietal cells, G cells and enterochromaffin - like cells (ECLs). The first cells of all of the glands are foveolar cells in the neck region--also called mucous neck cells that produce mucus . This is thought to be different from the mucus produced by the gastric mucosa . </P> <P> Fundic glands found in the fundus and also in the body have another two cell types--gastric chief cells and parietal cells (oxyntic)). </P>

The cells of the gastric glands of the stomach include
