| 摘 要： | 透射电镜下观察长江华溪蟹成熟精子的形态和超微结构。精子呈椭球形，无鞭毛，具数条由核延伸而成的辐射臂精子。由球形的顶体，膜复合体，核杯及辐射臂组成，顶体由头帽，亚帽带，丁体囊及中央管组成。在中央管的基部发现有中心粒。核膜与质膜紧贴在一起形成了精子的界膜。

| Abstract: | The sperm ultrastructure in the crab Sinopotamon yangtsekiense was studied with transmission electron microscope (TEM).The sperm is aflagellate.The mature sperm primarily consists of a spherical acrosome,nuclear cup and membrane complex.The acrosome consists of an apical cap,subcap zone,a PAS positive acrosome vesicle and a cylindrical central canal.The acrosome is surrounded by nuclear cup except the apical cap.The nuclear cup shows feulgen positive.Centrioles lies at the base of the central canal.The radial arms are shorter and formed by nuclear processes. |
