HISTOLOGY OF INTEGUMENT OF NEOECHINORHYNCHUS BERINGIANUS
Histological structure of tegument and skin musculature of acanthocephalan described from the nine-spined stickleback from the southern part of Magadan region was studied. In general the tegument's structure was similar to that, of other described species of the genus. Metabolic centers were represented by radial fibrous layer of tegument and lemnisci. Heterogeneity of tegument nuclei and lemnisci of unknown nature were found. Basement lamina and proboscis hooks contained collagen in their structure.
