Anatomical and topographic features of the structure of the ulnar nerve of the white swiss shepherd

Abstract

Currently, in veterinary morphology, special attention is paid to the study of the peripheral nervous system in companion animals in species and breed aspects. Dogs of the White Swiss Shepherd breed are especially valued in breeding for their conformation and watchdog qualities, and to this day they are a breed of dogs about whose anatomy there is not enough information. The purpose of our study is to study the anatomical and topographic features of the structure of the ulnar nerve in the White Swiss Shepherd Dog. The studies were carried out on the basis of the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. The corpses of dogs of the White Swiss Shepherd breed aged from two to four years served as dated material. In total, ten corpses were examined, weighing 39.5 ± 1.0 kg. As a result of the study, it was found that in White Swiss Shepherd dogs, the ulnar nerve and its branches in the White Swiss Shepherd Dog participate in the innervation of the zeigo and autopodia, passing mainly along the medial surface of the forearm. Also, during the study, the morphometric indicators of the ulnar nerve and its branches were established.
