Smooth muscle
Smooth muscle located in the wall of the digestive tract is arranged in distinct circular and longitudinal layers. In the upper right of the field, the longitudinally oriented fibers are cut in cross section while the remainder of the field contains circularly oriented fibers sectioned longitudinally. 1000x
