A preliminary study on histology of digestive system of the Batrachupers pinchonii(山溪鲵消化系统组织学的初步研究)
采用常规石蜡切片和扫描电镜，观察了山溪鲵消化系统组织结构和粘膜表面.结果表明，除口腔外，消化道管壁由粘膜层、粘膜下层、肌层和浆膜构成.消化道各部分的差别主要在粘膜层和肌层：食道粘膜为复层柱状上皮，无纵肌层；胃、肠粘膜上皮为单层柱状上皮，胃肠肌层有内环外纵两层平滑肌组成.而且粘膜上皮细胞表而细微结构、粘膜中腺体的分布情况、肌层的相对厚度等在消化道各部分也存在差异.肝细胞以群集为主，肝小叶不明显 ，胰为弥散型....
