Technique of studying of the arterial course of birds
During the bird arterial system studying the researcher meets some troubles. Unlike mammals artery wall of birds is more thin and less strong. This should be considered in order to avoid vessels rupture when the mass flow into the bloodstream. In the pelvis of birds thoracic, lumbar and sacral regions of the spine are completely grown together, forming almost a single bone conglomerate. This fact makes it almost impossible to access the aorta from the dorsal side of the spinal column through the incision, as it is done in mammals. We offer access to the aorta in birds from the ventral side of the body. To do this, it is needed to put the body on the back, to make sagittal cut of the skin near the keel, exposing large pectoral muscles and the abdominal muscles on the both sides. With two scissors cuts, running parallel to the vertebral column, cut the left and right costae, the coracoids bones and clavicle, and then remove sternum with the covering muscles. After such manipulation, we get access to all of the abdominal organs, including the heart. Opening the heart shirt, gently pull the heart along with the caudal vessels and catheterize the initial portion of the aorta. With such access only superficial, deep pectoral and intercostals arteries are injured, which are readily doped using haemostatic clips. For the arterial system of bird’s injection conventional methods used in the study of the cardiovascular system of mammals can be used. However, due to the fact that the walls of bird’s arteries are much thinner than that of mammals, injection must be prepared of a liquid consistency. The proposed method of studying the bird’s arterial branches is universal and can be applied not only for scientific purposes, but also for the production of educational products at the course "Anatomy of poultry." It can also help the physiologists and path physiologists during the study of the features of circulation of various organs and tissues in birds.
