During this period, all the layers of stomach were not well organized. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.

Inferiorly, it has no floor of its own as it is continuous with the pelvic cavity. The stomach and stomach wall | Macmillan Cancer Support Beneath the gastric mucosa is a thin layer of smooth muscle called the muscularis mucosae, and below this, in turn, is loose connective tissue, the submucosa, which attaches the gastric mucosa to the muscles in the walls of the stomach.
