| Abstract | This study presents the histological features of the valvular apparatus of the heart of Anglo-Nubian goats. There were studying aortic semilunar valve, tricuspid valve, and morphometric data of its histological structures. As dated material, we used the hearts of Anglo-Nubian goats aged one year and older, obtained at slaughter from Gzhel Podvorie Farm in the Moscow, Russian Federation. A total of 10 animal corpses were examined, from which samples were taken by fine anatomical preparation in the form of one example of the cusp of the semilunar aortic valve and the tricuspid valve. For achieving this task, a complex of traditional histological methods and stains was used: Trichrome, according to Masson, toluidine blue, and Schiff-iodic acid, according to McManus. The Anglo-Nubian goat's semilunar heart valve's leaflets consist of aortic (fibrous), spongy (spongy), and ventricular layers. The aortic layer has formed by collagen and elastic fibers. The spongy layer has formed by loose small-cell connective tissue. The ventricular layer of the cusps of the semilunar aortic valve has also been formed by connective tissue and is much smaller than the aortic layer. The leaflets of the tricuspid heart valve of an Anglo-Nubian goat have formed by fibrous plates of dense high-celled fibrous connective tissue. In the spongy layer of which there are blood vessels of the mixed and muscleless type. The surfaces of the cusps of both valves had covered with endothelium. The obtained morphometric and histological data indicate the species and breed peculiarities of the heart of an Anglo-Nubian goat and the differences in the structure of the semilunar and atrioventricular valves at the micro-level. |
