| 摘 要： | 用扫描电子显微镜技术研究了菲律宾蛤仔唇瓣的表面结构。结果表明 :菲律宾蛤仔唇瓣分为光滑面和褶皱面。光滑面细胞排列紧密 ,细胞表面有大量的微绒毛 ,纤毛较少 ,呈簇状分布 ;褶皱面具沟和嵴 ,嵴上被覆浓密的纤毛。光滑面和褶皱面的纤毛在末端膨大呈勺状 ,两面都有大量黏液细胞分布。纤毛和黏液在食物选择和运输中起重要作用

| Abstract: | The exterior structure of the labial palps of Rud it apes philippinarum was studied using the scanning electron microscope. The res ults indicate that a labial palp of the Ruditapes philippinarum has a ridged surface and a smooth surface. The cells of the smooth surface are arranged comp actly.There are fewer cilia on the smooth surface and they are distributed in a cluster.There are a great number of microvilli on the cells.The ridged surface i s folded into deep ridges and grooves.The ridges are covered with dense cilia. T he end of each cilium on the smooth and ridged surfaces expands and is scoop sh aped. There are a great many mucous cells on both surfaces of the labial palps.T he cilia and the mucous cells play important roles in choosing food particles an d delivering food to the mouth. |
