| 摘 要： | 应用切片技术研究了粗糙沼虾鳃的组织学。结果表明：粗糙沼虾具有7对鳃，每个鳃均由鳃轴和数条鳃叶构成。鳃轴主要由结缔组织构成，背、腹面分别具有一条入鳃血管和出鳃血管。鳃轴内含有鳃腺、肾原细胞和营养细胞。鳃叶是鳃的基本呼吸单位，平行着生在鳃轴的两侧。鳃叶壁由单层扁平上皮及几丁质层构成；鳃叶边缘具有入鳃边缘血管和出鳃边缘血管。

| Abstract: | The histology of the gills of M.asperulum was studied with section technology. The result shows that M.asperulum has seven pairs of phyllobranchs, and every one of them consists of a gill axis and many gill lamellae. The gill axis is composed of connective tissue, and has a vas afferens in its dorsal side and a vas efferens in its ventral side. The gill axis also contains a lot of gill glands,nephrocytes and nurse cells. The lamella is a basic respiratory unit of gill, and its wall is composed of a single layer of flattened epithelial cells and cuticle layer, and has afferent and efferent marginal vessels in its margin. |
