Morphologic description of the collateral branches from aortic arch and its main ramifications in Leopardus pardalis

Abstract

In order to contribute for the knowledge of the anatomy of the ocelot (L. pardalis), it was studied an animal from the Mina de Bauxita Paragominas/PA - Vale do Rio Doce, donated, after natural death, to the Instituto de Saúde e Produção Animal - ISPA of the Universidade Federal Rural da Amazônia - UFRA. After filling the arterial system with red colored latex, the dissection was performed to observe the arrangement of the branches of the aortic arch. The only branches that emerged from the aortic arch were the brachiocephalicus trunk and the left subclavian artery. From the brachiocephalicus trunk first came the left common carotid artery and the right subclavian artery emerged in the trunk with the right common carotid artery. The left subclavian artery originated the following branches: vertebral artery, internal thoracic artery, the costocervicalis trunk and cervical superficial artery. The right subclavian artery had a cranial origin and had a homologue trajectory to the left, resulting in similar branches. Keywords: Ocelot, aortic arch, comparative anatomy
