| 摘 要： | 运用石蜡切片和扫描电镜技术研究了栉孔扇贝和太平洋牡蛎的唇瓣结构。结果表明，2种贝的唇瓣结构都是中间一层结缔组织，两侧被覆纤毛柱状上皮，结缔组织中富含血腔隙。栉孔扇贝唇瓣的粘膜上皮由柱状细胞和杯状细胞组成；而太平洋牡蛎由柱状细胞、杯状细胞和嗜酸性粒分泌细胞组成。扫描电镜下，2种贝唇瓣的褶皱面呈现沟和嵴，纤毛浓密；光滑面纤毛较少。太平洋牡蛎唇瓣褶皱面的游离边缘部分和光滑面有大量的球状突起，这是杯状细胞所在处。纤毛和粘液在食物分栋和运输中起重要作用。

| Abstract: | The structure of labial palps of Chlamys farreri and Crassostrea gigas were studied using light microscopy and scanning electron microscopy. The results show that each labial palp consists of a layer of connective tissue covered on both sides by columnar ciliated epithelium setting on a thin basement membrane. There are many blood spaces within the connective tissues. The epithelum of the labial palps of C.farreri has 2 cell types:columnar ciliated cell and mucous cell, while that of C.gigas consists of columnar ciliated cell,mucous cell as well as eosinophilic cell. Under scanning electron microscopy, the ridged surfaces of the palps of the 2 bivalves are folded into deep ridges and grooves, and the cilia is robust. There are a lot of spherial granules, which are mucous cells, on the smooth surfaces and near the free edge of the ridged surfaces of the palps in C.gigas. The cilia and the mucous cells play important roles in sorting food particles and delivering food to the mouth. |
