Anatomo-topogaphic features of the vascularization of the pharynx in a goat of the anglo-nubi breed

Abstract

The pharynx is one of the first links in the respiratory and digestive systems. Knowledge of the peculiarities of the topography of the main highways of the pharynx, as well as their branches, is necessary for a veterinarian in the diagnosis, prevention and treatment of pathologies of the respiratory and digestive systems.
The aim of the study was to study the anatomical and topographic features of the pharyngeal blood supply in an AngloNubian goat. The studies were carried out on the basis of the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. To study the blood supply to the pharynx, 15 corpses of Anglo-Nubian goats were examined and the following techniques were used: fine anatomical dissection, vaso-radiography and the manufacture of corrosive preparations.
According to the results of the study, it was found that of all parts of the pharynx, the highest intensity of vascularization in the Anglo-Nubian goat is observed in the oropharynx. The anatomical and topographic features of the arteries of different parts of the pharynx were established, it was determined that the arteries of different parts of the pharynx in their architectonics are diverse and variable both in terms of the type of branching and the breadth of the vascularization field and the degree of their tortuosity.
