Electron Microscopical Study of Spermatozoa of the Cestode Dilepis undula (Cyclophyllidea, Dilepididae)
The fine structure of spermatozoon of the dilepidid cestode Dilepis undula is described. The main structural elements of the sperm cell are: 1) plasma membrane and underlying single row of cortical microtubules; 2) a single axoneme of the unique platyhelminth 9+˝1˝ type; 3) periaxonemal sheath compo...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The fine structure of spermatozoon of the dilepidid cestode Dilepis undula is described. The main structural elements of the sperm cell are: 1) plasma membrane and underlying single row of cortical microtubules; 2) a single axoneme of the unique platyhelminth 9+˝1˝ type; 3) periaxonemal sheath composed of the crystalline-like material; 4) elongated electron-dense nucleus; 5) crested body. The similarities and differences between the ultrastructure of spermatozoa of D. undula and that of some other cestodes, are briefly discussed. |
