| 摘 要： | 利用组织学方法对丽纹龙蜥的消化管进行了观察,结果显示:消化管壁由粘膜层、粘膜下层、肌层和外膜组成。食管粘膜为复层扁平柱状上皮、胃、小肠和直肠上皮为单层柱状上皮。管壁皱襞的形态、腺体分布情况、肌层的相对厚度等在消化道各部存在差异。小肠具有明显的空肠分化。研究表明丽纹龙蜥消化管的结构特征与其食性相适应,与鸟类和哺乳类动物相比,具有一定的不完善性和低等性。

| Abstract: | The digestive tract of Japalura splendida was observed by histological method.Results show that its digestive tract is made up of four concerntric layers,which are the mucosa,submucous,muscularis and adventitia respectively.The epithelium of digestive tract is simple columnar cells except that of esophagus is stratified squamous epithelium.The mucosal plica,gland's distribution and thickness of muscularis are different in the different part of the digestive tract.The jejunum is very clear in the small intes... |
