<Li> The inner oblique layer: This layer is responsible for creating the motion that churns and physically breaks down the food . It is the only layer of the three which is not seen in other parts of the digestive system . The antrum has thicker skin cells in its walls and performs more forceful contractions than the fundus . </Li> <Li> The middle circular layer: At this layer, the pylorus is surrounded by a thick circular muscular wall which is normally tonically constricted forming a functional (if not anatomically discrete) pyloric sphincter, which controls the movement of chyme into the duodenum . This layer is concentric to the longitudinal axis of the stomach . </Li> <Li> Auerbach's plexus (AKA myenteric plexus) is found between the outer longitudinal and the middle circular layer and is responsible for the innervation of both (causing peristalsis and mixing) </Li> <Li> The outer longitudinal layer is responsible for moving the bolus towards the pylorus of the stomach through muscular shortening . </Li>
