摘要
运用大体解剖和常规组织学方法 ,对 1 4尾全长 3 0 0~ 3 80 mm鲤鱼的消化管的形态进行了观察。结果表明 ,鲤鱼的消化管不发达 ,管壁由内向外分为黏膜、黏膜下层、肌层与外膜四层。口咽腔的黏膜内含有较多的味蕾 ;食管黏膜上皮的形态依皱襞部位而异 :皱襞顶端为复层扁平上皮 ,侧部及基部则由数层粘液细胞和少量上皮细胞构成 ;食管后紧接前肠 ,无胃 ;除直肠外的肠壁固有层中均有不发达的肠腺分布。
The morphology of 14 Cyprinus carpio Linne digestive tract whose lenth were 300~380 millimeter was observed by using common anatomical and histological methods. The results suggested that the digestive tract in Cyprinus carpio Linne was undeveloped and its wall could be divided into mucosa, submucosa, muscle layer and adventitia from the inner to the outer. There are many taste buds in mucosa of cavum buceale and pharynx, the shape of mucosa epithelium in esophagus was different from the position of its plicae, which was stratified squamous epithelium at the top of plicae and was consisited of many mucous cells and a few squamous cells both at the side and bottom of plicae. Esophagus was followed by foreintestine, there was no stomach between esophagus and foreintestine. There were undeveloped intestinal glands in lamina propria of the whole intestinal wall except for intestinum retum.
