The muscle layers of human stomach in 51 cases of stomach specimens were studied after stripping the mucosa. Specimens included 5 cases of totally resected and 46 of partially resected specimens. All specimens have no gross pathological finding on the gastric portion.<BR>1. Oblique muscle: The oblique muscle was divided into two groups. The first group originates from circular muscle of the esophagus and distributes over the gastric corpus. And the second group distributes over only the fundus and is independent to circular muscle of esophagus.<BR>The oblique muscle of gastric corpus runs down on anterior and posterior gastric walls and pararell to the lesser curvature, forming a cleft between anterior and posterior bundle, to the end of the gastric corpus.<BR>The cleft seems to be corresponded to so-called "Magen-strasse".<BR>2. Border between corpus and antrum: The first group, the muscle bundle which runs most closely to the lesser curvature and down to the most distance become mixed into the circular muscle bundle there. Therefore, the author named this most inner oblique muscle "the longest oblique muscle." In the pyrolic side from the circular muscle bundle, no oblique muscle can be seen. So, the author divided corpus and antrum by this circular muscle bundle, and named this circular muscle bundle "the border circular muscle bundle".<BR>3. Circular muscle: The circular muscle was divided into two groups. The one was mixed with oblique muscle bundle on the part near greater curvature and distributes over gastric corpus. The other distributes over the antrum without mixture of oblique muscle. Circular muscle was absent over fundus.
