Description:: System: Gastrointestinal Organ: Esophageal cardiac junction Disease process: Normal Species: Human Highest magnification: 20x Stain: H&E Note the epithelial transition from stratified squamous non-keratinized (esophagus) to simple columnar (gastric). There are two sets of glands: esophageal glands (in the submucosa) vs. cardiac gastric glands (in the mucosa). In the muscularis layer the “sphincter” is an expansion of the middle oblique layer in the gastric muscularis which forms an incomplete sphincter, i.e., “sling” or valve + skeletal muscle (crura of diaphragm). The cells that line the gastric glands in the cardiac region of the stomach: they are all mucous producing cells. The luminal surface and the gastric pits are also lined by surface mucus cells.
