Sistematização, distribuição e território da artéria cerebral média e cerebroetmoidal na superfície do encéfalo em peru (Meleagris gallopavo)
Carvalho, Amarílis Díaz deCampos, Rui
Background: The cerebral arteries constitute the main blood transportation via to the brain and play a fundamental role in the maintenance of normal cerebral activities. There are a few studies about the encephalic irrigation in the wild and exotic species. This study aims to describe and systematize the middle cerebral artery and cerebroethmoidal artery of Meleagris gallopavo, to determine a standard model and territorial area of irrigation, and the main variations in this species.Materials, Methods & Results: For this research, 30 brain with the cervical spinal cord segment of 10 male and 20 female young and adult turkeys (Meleagris gallopavo) were used. Discarded animals were provided from Doux Frangosul breeding center, located in Caxias do Sul city, State of Rio Grande do Sul, Brazil, 2006. Animals were euthanized with T 61, with an intravenous injection. After the removal of the skin, the sternum was removed, the common carotid arteries were cannulated through the brachycephalic trunks. The arterial system of the 30 animals were rinsed with saline solution with heparin and filled with latex colored in red. Animals remained immersed for one hour in running water, and next, the neck was sectioned. Next, a bone window was opened in the skullcap. Pieces were fixed in 20% formaldehyde for seven days, and after this period, the brain was removed from the cranial vault...(AU)
