| 摘 要： | 采用解剖和光镜技术观察了美洲黑石斑鱼消化道的形态及组织学结构。消化道由口咽腔、食道、胃、肠构成。口咽腔较大,具颌齿、腭齿及犁齿;舌由基舌骨突出部分覆盖粘膜构成。食道、胃及肠均由粘膜层、粘膜下层、肌层及外膜构成。食道粘膜层绒毛分柱状上皮区及扁平上皮区,扁平上皮区表面为杯状细胞层;食道粘膜下层中有食道腺。胃呈V形,由贲门部、胃体部及幽门部组成,胃壁粘膜层上皮为单层柱状上皮,胃腺位于贲门部与胃体部的固有层中。肠细长,呈S型,由前、中、后肠构成,粘膜层向肠腔突起形成肠绒毛,粘膜上皮为单层柱状上皮,上皮游离面有微绒毛密集排列而成的纹状缘,上皮中含有杯状细胞,且杯状细胞的数量从前向后呈递减趋势;肠长/体长约为1.6。胃与小肠相接处有3对指状幽门盲囊,幽门盲囊的组织学结构与肠相同。

| Abstract: | The morphological and histological structures of the digestive tract in Centropristis striata were observed by optical microscopes.The digestive tract includes the orol-pharyngeal cavity,esophagus,stomach and intestines.The orol-pharyngeal cavity is big;there are jaw teeth,palato-teeth and vomerine teeth;tongue consists of basihyoid covered by mucosa.The esophagus,stomach and intestines stratified into mucous membrane layer,submucosa,muscularis and outer membrane.Esophageal mucosa layer villi fell into colu... |
