本文描述了白背无齿蚌鳃上四种纤毛的微细结构及其与拍动方向的关系。纤毛包含9条外纤维、9条次级纤维和2条中心纤维，如先前在其他材料中所述。每一个外层纤维是一个具有一个亚纤维承载臂的双峰。一对特殊的外纤维（编号5和6）通过桥连接在一起。两条中央纤维被一个中央鞘包围;在这个区域也存在一个单一的，小的中间纤维。不同组的纤维通过从外部延伸到次级纤维以及从次级纤维延伸到中心鞘的径向连接件连接在一起。基体由9根三重纤维组成的圆柱体组成。从它的一侧突出的是一个密集的圆锥形结构，称为基底足。外纤维的圆柱体从基体延伸到纤毛，穿过一个复杂的过渡区，在该过渡区中，在不同的水平上发生五种不同的结构变化。有两组与基体相关的纤维：一对从每个基体向下延伸到细胞中的条纹状小根，以及平行于细胞表面延伸的细管状纤维系统。在所有四种类型的纤毛检查的细微结构和方向的节拍之间的关系是相同的。节拍平面垂直于中心纤维的平面，有效行程朝向外部纤维5和6之间的桥，并且朝向基体上的脚。
This paper describes the fine structure and its relationship to the direction of beat in four types of cilia on the gill of the fresh-water mussel Anodonta cataracta. The cilia contain nine outer, nine secondary, and two central fibers, such as have been described previously in other material. Each outer fiber is a doublet with one subfiber bearing arms. One particular pair of outer fibers (numbers 5 and 6) are joined together by a bridge. The two central fibers are enclosed by a central sheath; also present in this region is a single, small mid-fiber. The different groups of fibers are connected together by radial links that extend from the outer to the secondary fibers, and from the secondary fibers to the central sheath. The basal body consists of a cylinder of nine triplet fibers. Projecting from it on one side is a dense conical structure called the basal foot. The cylinder of outer fibers continues from the basal body into the cilium, passing through a complex transitional region in which five distinct changes of structure occur at different levels. There are two sets of fibers associated with the basal bodies: a pair of striated rootlets that extends from each basal body down into the cell, and a system of fine tubular fibers that runs parallel to the cell surface. The relationship between fine structure and direction of beat is the same in all four types of cilia examined. The plane of beat is perpendicular to the plane of the central fibers, with the effective stroke toward the bridge between outer fibers 5 and 6, and toward the foot on the basal body.
