[Ultrastructure of lemnisci in Polymorphus magnus (Acanthocephala, Polymorphidae)].
The ultrastructure of lemnisci in female acanthocephala (Polymorphus magnus) has been studied. Lemnisci are shown to be specific metabolic centers, where lipids are accumulated and utilized. Lipids get to these centers either by means of absorption by praesomal tegument or from the pseudocoel through the system of invaginations of cytoplasmic membrane limiting the lemnisci. Lipids are supposed to be transported after conversion into the praesoma tegument and secreted to its surface through the striated layer canals.
