乌鳢消化管的形态学及组织学观察

The Observation on Morphology and Histology of Digestive Tract in Ophicephalus argus

摘要: 本研究采用解剖学和组织学方法观察了乌鳢消化管的结构。结果表明，乌鳢消化管包含口咽腔、食道、胃、幽门盲囊及肠道五个部分。消化管由粘膜层、粘膜下层、肌层及外膜四部分组成。口咽腔和食道的粘膜上皮为复层扁平上皮，胃、幽门盲囊和肠道的粘膜上皮为单层柱状上皮，胃粘膜上皮说有少量粘液细胞分布，其他消化管粘膜上皮中有大量杯状细胞分布。本文旨在丰富乌鳢生物学的研究内容，为乌鳢人工养殖奠定基础。

Abstract: The anatomical and histological methods were used to observe the structures of the digestive tract in Ophicephalus argus. The digestive tract in Ophicephalus argus is composed of oral-pharyngeal cavity, the esophagus, the stomach, the pyloric caecum, and intestine, and the digestive tract with four layers: mucosa, submucosa, muscularis and serosa. The stratified epithelium of buccopharynx and oesophagus was located with numerous goblet cells. A single-layered columnar epithelium of the pyloric caecum, and intestine were located with many goblet cells too. A single-layered colum-nar epithelium of the stomach was located with fewer goblet cells. The study enriched the research content of the Ophicephalus argus. It is the foundation of artificial breeding of the Ophicephalus argus.
