Esophagus-stomach junction, unspecified source.
This slide represents a longitudinal section of esophagus joining the stomach. This slide rewards naked-eye examination to establish the orientation of the mucosal elements and underlying CT and muscle. Esophageal mucosa is identified by its stratified squamous epithelium, while stomach mucosa (on either side of the opening into the esophageal lumen) is lined by simple columnar epithelium. Lymphoid tissue is found deep to the epithelial junction. Deeper glandular tissue may represent either esophageal glands or tangential cut through gastric glands; these can be distinguished by the nature of adjacent CT and muscle.
