Arterial vascularization of the nasal mucosa Yorkshire piglets

Abstract

Pig breeding in the Russian Federation is one of the leading branches of agricultural products. In large industrial pig breeding complexes, part of the diseases in livestock is associated with the respiratory system. This is noted in statistical reports on newborn animals in pig breeding complexes of the North-Western region of the Russian Federation. The nasal cavity in animals performs a number of vital functions, which include heating and humidifying the incoming air. The work was performed at the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. The corpses of Yorkshire piglets aged 10-14 days were used as the test material. In total, seven corpses of piglets delivered from the pig breeding complex of the Leningrad region were examined. Arterial vascularization of the nasal mucosa in Yorkshire piglets is carried out due to the cuneiform artery, which is a branch of the internal maxillary artery. In the studied piglets, the diameter of the cuneiform artery averaged 1.25±0.15 mm– In the nasal cavity, this artery passes through the cuneiform opening, and in the area of the last molar is divided into three branches. The first branch is the artery of the nasal septum, its diameter on average is 0.58 ± 0.05 mm; the second branch is the artery of the ventral nasal conch, its diameter on average is 0.73± 0.06 mm; the third branch is the artery of the dorsal nasal conch, its diameter on average was 0.54± 0.04 mm. Arterial branches of the first, second and third order in the mucous membrane of the nasal septum throughout have a constant diameter and are located parallel to each other.
