| 摘 要： | 采用解剖和光镜技术研究了全长9.70~17.48 cm唇鱼(Hemibarbus labeo)消化系统形态学和组织学特点。结果表明:唇鱼消化系统包括消化道和消化腺两部分。消化道包括口咽腔、食道、肠和肛门,肠可分为前肠、中肠和后肠。消化腺包括肝胰脏和胆囊。唇鱼消化系统特点:口下位呈马蹄形,吻长而略尖,唇厚,肉质,下唇尤为发达。食道粗短,肌层发达,内壁上有较深的纵向褶,黏膜层有大量的杯状细胞。肠呈S型,分前肠、中肠、后肠,前肠部较阔,内褶皱层很深,隐窝很窄,褶与褶相连成网状,褶的分支不发达,中肠及后肠褶的深度渐弱,肠后部末端褶层最浅。肝不分叶,呈长条形,一长形的裸露胆囊被肝包围,肝小叶是唇鱼肝脏的基本组织结构。肝胰脏不分开,胰脏弥散,位于肝、脾及肠管之间。

| Abstract: | The characteristics of morphology and histology of digestive system of skin carp Hemibarbus labeo with the total length of 9.70—17.48 cm were studied by using anatomy and light microscope.The results showed that the digestive system is made up of digestive tract and accessory digestive glands.Except oropharynx and esophagus,the digestive tract can be divided into three parts: foregut,midgut and hindgut,and the digestive glands refer to hepatopancreas and gall-bladder.The digestive system is characterized by: a low U-shape mouth,a long pointed snout,two flesh lips(especially the lower lip) are very thick;esophagus chunky with well-developed muscle layer,of which the inner wall is deep and mucosal layer has a large number of goblet cells;the S-shape intestine can be divided into foregut,midgut and hindgut;the wide foregut has deep vertical folds,narrow recess,the connected folds is net-shaped,the branch of folds are undeveloped,the folds of midgut and hindgut shallow gradually,and the end of gut is the thinnest.The diffuse liver wrapped in a long gall-bladder can not be divided into different lobes.The hepatic lobule is the basic structure of the liver.a hepatopancreas combines the digestive functions of the liver and pancreas in vertebrates.The pancreas are diffuse and located among the liver,spleen and intestine. |
