Název v původním jazyce

Morphology and fine structure of the Russian sturgeon, Acipenser gueldenstaedtii (Acipenseridae, Chondrostei) spermatozoa

Popis výsledku v původním jazyce

Spermatozoa morphology and fine structure were studied in the Russian sturgeon, Acipenser gueldenstaedtii (Acipenseridae, Chondrostei) spermatozoon using scanning and transmission electron microscopy. The spermatozoon is composed of an elongated head (length: 6.84 +/- 0.04 mu m) with an acrosome (1.18 +/- 0.01 mu m length and 1.05 +/- 0.01 mu m width), a cylindrical midpiece (length: 1.64 +/- 0.03 mu m) and a flagellum (length: 49.42 +/- 0.37 mu m). Eleven to 12 postero-lateral projections (length: 0.65+/- 0.02 mu m) were observed at the posterior edge of the acrosome. Three endonuclear canals was observed from the acrosome to the implantation fossa. In the midpiece, 46 mitochondria were observed as well as (i) a proximal centriole close to the implantation fossa and (ii) a distal centriole at the base of the axoneme. The flagellum consisted of nine peripheral microtubules and a central pair surrounded by the plasma membrane, which was extended while developing a pair of lateral fins
