[Formation sources and topographic characteristics of the pelvic plexus in furry animals of Canidae and Mustelidae families].
Using preparation methods, the topography and the formation sources of pelvic plexus (PP) were studied in animals of Canidae (silver-black fox, blue fox) and Mustelidae (sable, American mink) families. Maximal differences in PP topography and PP-forming nerves were found between species (Canidae-Mustelidae), whereas the intraspecies differences were less pronounced. Intraspecies sex-associated differences in PP topography are associated with only quantitative parameters, while those in PP formation sources and in peculiarities of PP-forming nerves' branching pattern are qualitative in nature. There is a distinct correlation between PP structural type (diffuse, compact, mixed) and peculiarities of its ganglionic apparatus: in diffuse type the juxta- and intraogan position of ganglia is prevalent, while in compact type the extraorgan position is more common.
