为探讨棘胸蛙消化系统结构与食性功能的关系,采用解剖学、组织学、组织化学方法对其消化系统进行了宏观及显微结构观察.结果 表明:棘胸蛙口咽腔含有纤毛柱状上皮、丰富的单细胞腺体和多细胞舌黏膜腺、颌间腺体,还有味蕾结构.食道具复层纤毛上皮,无味蕾,食道腺极发达.胃上皮黏膜层中有大量胃小凹和杯状细胞,具黏膜肌;胃腺发达,胃腺细胞胞质含嗜酸性颗粒,分泌黏液类型在贲门、胃体、幽门中主要呈Ⅲ-Ⅳ-Ⅲ型变化.十二指肠绒毛细长密集,回肠、直肠逐渐缩短,在黏膜层的固有膜中无小肠腺分布,肠壁较薄,杯状细胞在肠道各段较丰富,呈高—低—高变化.直肠黏膜上皮中含有巨型杯状细胞,固有膜有管状直肠腺散...

Macro and microstructure of the digestive system were investigated using the anatomy,histological,histochemical methods in order to investigate the relationship between the function of digestive system and feeding habits of Rana spinosa.The results showed that the digestive tract of R.spinosa was made up oropharyngeal cavity,esophagus,stomach,intestine,and cloaca;the main digestion gland consisted of liver and pancreas.The oropharyngeal cavity contains ciliated epithelium,glandular cells and multicellular glands of single tongue mucosa.The esop...
