forestomach-glandular stomach junction
The distinct low fold of tissue that separates the non-glandular area of the stomach (forestomach) from the glandular stomach; the limiting ridge extends circumferentially from the large curvature of the stomach to the small curvature, just below the esophagus; at the esophagus, the course of the limiting ridge bends into a U-shape and almost surrounds the esophageal opening.
