There are actually FOUR layers of muscle in the stomach. For an effective explanation you need to find a sectional view of the stomach. 1) the muscularis mucosae - a very thin layer of smooth muscle that functions in altering the surface area of the stomach by moving the villi back and forth. 2) Muscularis Externa - there are THREE layers of this muscle in the stomach (compared to only 2 layers in the small intestine.)The following are ordered from innermost layer to outermost layer. >innermost oblique >middle circular >outer longitudinal Happy studying!
