As the mucosal, submucosal and serosal layers were more or less uniformly thick in all parts of the stomach, any variation in wall thickness would be due to thickening of the muscular coat. In the remainder of the stomach the wall thickness was 2.0 to 3.0 mm. The pyloric ring formed the aboral part of the muscular thickening. It was concluded that there was a tube of thickened pyloric musculature, approximately 3.0 cm in length and incorporating the pyloric ring, in adult morbid anatomical specimens.
