The submucosa is made up of dense connective tissue
The muscularis of stomach contains an additional layer of oblique muscles other than an inner circular and outer longitudinal layer of smooth muscle

The mucosa is composed of simple epithelium cells and a thin connective tissue - areolar tissue. The layer of areolar connective tissue is called lamina propria.
