Abstract

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.

板鳃软体动物鳃纤毛精细结构与搏动方向的关系。
本文描述了淡水贻贝(Anodonta cataracta)鳃上四种纤毛的精细结构及其与拍打方向的关系。纤毛包含九根外层纤维、九根次级纤维和两根中心纤维,如前面在其他材料中描述的那样。每根外层纤维是一根带有一根亚纤维承载臂的双线。一对特殊的外层纤维(5号和6号)通过桥接连接在一起。两个中心纤维被中心鞘包围;在这个区域也有一个单一的,小的中纤维。不同组的纤维通过径向连接在一起,径向连接从外层延伸到次级纤维,从次级纤维延伸到中心鞘。基体由九根三联体纤维组成的圆柱体。从它的一侧突出的是一个致密的圆锥形结构,称为基足。外纤维的圆柱体从基底体继续进入纤毛,经过一个复杂的过渡区,在这个过渡区中,在不同的水平上发生了五种不同的结构变化。与基生体相关的纤维有两组:一对有条纹的细根,从每个基生体延伸到细胞内;一组细管状纤维,平行于细胞表面。四种纤毛的精细结构与搏动方向之间的关系是相同的。拍击平面垂直于中心纤维的平面,有效拍击方向为外侧纤维5和6之间的桥,以及基底上的足部。
