Figure 2

The pyloric sphincter (PS) divided according to the direction of the longitudinal bundles entering it. (A) Some longitudinal bundles (white arrow) divided the PS into several parts in a longitudinal section including the greater curvature (GC). The divided parts (black arrows) of the PS were not separated completely, but were connected to each other. (B) Some longitudinal bundles (white arrows) entering the PS were connected to the aboral circular bundles (black arrow) of the PS in a longitudinal section including the lesser curvature (LC) and GC. cD circular bundles of the duodenum.
