Cardiac Region of the Stomach

Author: Dr. Thomas Caceci


This is the "cardiac" region of the stomach, so called because it lies near the heart. The depressions in the gastric surface, the gastric pits (GP) are lined with a simple columnar epithelium devoid of goblet cells. Cardiac glands (CG) are found in this region; they make a mucous secretion for protection of the epithelium from erosion in the harsh environment of the stomach. Notice the location of the glands. They're not in the submucosa, but in the lamina propria. All three types of glands in the stomach are above the muscularis mucosae (MM). Therefore, they're anatomically part of the tunica mucosa.
