| Popis: | Aim of the study is to illuminate some data on gastric esophageal junction morphology in Guinea Pig brings explanations on mice unable to vomit. There are few literature data on the conformation and structure of the laboratory mouse esophagus and stomach. They try to explain why the mouse can not vomit. Deviating slightly to the left only in the cervical region the esophagus runs mainly in the cervical region the esophagus runs mainly mid sagittally along the dorsal aspect of the trachea. Its length is about 30 mm (3, 4). Through out its length the diameter is about 2 mm. Through out its length the diameter is about 2 mm. The epithelium of the esophagus is moderately to extensively cornfield. The submucosa is free of gland. Both layers of the muscular coat are made buddle of skeletal muscle. The esophagus enters the middle of the lesser curvature. The esophageal sphincter is a circular muscle that surrounds the base of the esophagus. At its lower edge, it has muscle fibers that insert into the limiting ridge. So when the sphincter contracts, it not only constricts the walls of the esophagus, it also pulls the sides of the limiting ridge's "U" together, thus hiding and tightly closing the esophageal opening. Muscle layer is formed on the entire length of skeletal muscle fiber |
