摘要：

[目的]观察东方蝾螈胃和小肠的组织结构。[方法]制作组织切片,利用显微镜观察组织结构。[结果]东方蝾螈的胃壁和小肠壁由内向外依次可分为黏膜层、黏膜下层、肌层、浆膜层4层,小肠黏膜下层不明显。黏膜层向腔内形成纵褶,且较厚,肌层主要由内环外纵2层平滑肌构成。小肠绒毛由黏膜上皮和固有膜向肠腔突出形成,在十二指肠段密集且较高,向远端(回肠端)渐疏渐短。[结论]东方蝾螈胃和小肠的形态结构较简单,胃肠壁较薄,肌层欠发达。

摘要：

[Objective]To observe the histological structure of the stomach and small intestine of Cynops orientalis.[Method]Slices of stomach and small intestine of Cynops orientalis were prepared,and then observed by microscope.[Result] The Stomach wall and small intestine wall of Cynops orientalis were made up of four concentric layers,which were mucosa,submucosa,muscular,serosa ento-ectad.The submucosa of small intestine wall was obscured.The thicker mucosal folds to cavity were formed.The muscular layer was constructed by circular fibers and longitudinal fibers.The intestinal villi was formed by mucosal epithelium and lamina propria which protrude to lumen of intestinal.The intestinal villi was intensive and higher near the duodenum,and becoming shorter and thin to the distal(terminal ileum).[Conclusion] The structure of stomach and small Intestine of Cynops orientalis is single.The wall of stomach and small intestine were thin,and the muscular layer was underdeveloped.
