Sources of vascularization of the tomatous cavity in the long-tied our living and the hawk

Abstract

Тhe purpose of our research is to study the peculiarities of the branching of arterial vessels of the thoracic and pelvic cavities in the long-tailed owl and the goshawk. The objects of the study were carcasses of adult wild birds, which were hunted by hunters under licenses in the spring-autumn period. For the manufacture of angiosteotopic preparations of the arterial system, self-hardening plastic of the acrylic series "Belokril" was used. High-grade oil paints were added to the monomer to give the vessels the desired color. As a result of our studies, we found that the aorta emerges from the left ventricle of the heart, forming the aortic arch and passing into the descending aorta, which is divided into the ascending aorta, the aortic arch and the descending aorta. The right and left brachiocephalic trunks extend from the ascending part of the aorta. From each brachiocephalic trunk the vertebral trunk, sternoclavicular, dorsal coracoid, and internal thoracic arteries sequentially depart. The main main vessel in the lumbar spine is the descending aorta, from which the external iliac, paired cranial renal and lumbar arteries depart. After the discharge of the external iliac artery, the descending aorta is called the middle sacral artery. From the middle sacral artery in the caudolateral direction, the sciatic right and left arteries depart, forming deep vascular impressions on the ventral surface of the kidneys. The middle and caudal renal arteries depart from the sciatic arteries into the corresponding lobes of the kidneys. After the sciatic artery leaves, the descending aorta is called the middle sacral artery, which runs caudally towards the cloaca and is called the middle tail artery.
