ABSTRACT
The muscle arrangements of esophago-gastric junction were observed in 30 human specimens. Muscles of the esophago-gastric junction consist of two layers-an outer longitudinal oblique layer and an inner circular oblique layer. At the top of esophageal vestibule 2 superficial muscle bundles may be identified. They are continuous with longitudinal muscle fibers of the tubular esophagus and runs to the stomach. The deep circular layer of the tubulovestibular junction is thicker than that of the tubular esophagus. It looks like a sphincter which lies 27.06 2.11mm above the cardiac incisure. At the middle segment of the esophageal vestibule some of the circular muscle fibers turn into spiral or loop forms. At the terminal portion of the vestibule two semicircular muscles separately localized towards the fundus and the lesser curvature of the stomach. They overlap at the back or at the front of the stomach. A small bundle opposite the gastric sling fiber demarcates the right margin of the esophago-gastric junction.
