Photograph of a hemisected human stomach. This photograph shows the mucosal surface of the posterior wall of the stomach. Numerous longitudinal gastric folds are evident. These folds or rugae allow the stomach to distend as it fills. The histologic divisions of the stomach differ from the anatomic division. The former is based on the types of glands found in the mucosa. Histologically, the portion of the stomach adjacent to the entrance of the esophagus is the cardiac region (cardia) in which cardiac glands are located. A dashed line approximates its boundary. A slightly larger region leading toward the pyloric sphincter, the pyloric region (pylorus), contains the pyloric glands. Another dashed line approximates its boundary. The remainder of the stomach, the fundlc region (fundus), is located between the two dashed lines and contains the fundic (gastric) glands.
• Fundic region (fundus), the largest part of the stomach, which is situated between the cardia and pylorus and contains the fundic or gastric glands (see Fig. 16.6)
