Abstract
The microanatomy and ultrastructure of the uterus in different stages of ontogenesis were studied in a cyclophyllidean cestode Lineolepis scutigera. In the early stages, developing embryos lie freely in the cavity of a single unbroken uterus, which is later fragmented into separate compartments. As a result, numerous spherical uterine capsules are formed; each of them contains one formed egg. Capsules represent a fragmented but actively functioning uterus. Muscular cells containing numerous lipid inclusions are located around them. In the final stages, placenta-like relationships are formed between eggs and the epithelium of capsules. A comparative morphofunctional analysis of uterine capsules in cestodes is presented. Attention is paid to the formation of close interactions between the uterine epithelium and developing eggs.
