![block10-1_13.jpg - Fig 5. 93W4506 Esophagus and stomach, H&E.The junction between the esophagus and stomach is shownhere. The esophagus is on the right, and the cardiac region ofthe stomach is on the left. The arrowhead shows the junction ofthem. The arrows point out the muscularis mucosa (MM) whichis continuous across the junction. The dashed line demonstratesthe boundary of the submucosa (S) and the muscularis externa(ME). The muscularis externa of the distal third esophagusconsists only of smooth muscle.
