Features of coronary arteries course and branching of the goats heart of anglo-nubian breed

Abstract

To measure the diameter of the vessels, we used an electronic Vernier Stainless caliper hardened with a division price of 0.05 mm. When describing the arteries of the heart, anatomical terms was carried out in accordance with the International veterinary anatomical nomenclature (fifth edition). During the study, we found that the heart of the Anglo-Nubian goats is supplied with blood by the coronary arteries, which originate from the aortic bulb in the location of the left semilunar and septum valves of the aortic valve. In respect of absences of the collaterals of the coronary arteries, it present the only source of vascularization of the myocardium. Coronary arteries of the heart of goats of the Anglo-Nubian breed are divided into right and left coronary (coronary) arteries, the first of which passes as part of the right interventricular furrow as a sub-synous and right diagonal artery, and the second - as part of the left interventricular furrow is divided into parochial and envelope arteries.
