Answer:
The muscularis mucosa is made up of smooth muscle, and is most prominent in the stomach. Within the muscularis externa, the circular muscle layer prevents food from traveling backward, while the longitudinal layer shortens the tract. The layers are not truly longitudinal or circular, rather the layers of muscle are helical with different pitches.
