The spermatozoon flagella of the fish tapeworm (Diphyllobothrium latum) is studied. The flagella consist of two axial filament complexes, which represent the unusual nine-plus-one pattern. The inside of the spermatozoon sheath is lined by single filaments. The mechanism of formation of this type of flagella is discussed. The spermatozoon flagella of the(More)
The sperm cell of Lebistes reticulatus during Spermatogenesis is studied. The nuclear differentiation correlate to the flagellar outgrowth. Differential distribution in the chromatin condensation corresponds to a new membrane synthesis at the centriolar side of the nucleus. The fan-shaped microtubular bundle in Juxtanuclear position is described and its(More)
The flame cell of the fish tapeworm (Diphyllobothrium latum) is investigated. In cross-section the flagella originating from the flame cell are hexagonal, except the incomplete ones facing the tubular wall. The function, as regards this unusual structure, is discussed. The axial filament complexes in one flame cell are arranged in opposite directions to(More)
