Abstract

Anatomic studies about Coati (Nasua nasua) are an interesting area, since the contribution to knowledge and development of biological system from this specie that is geographically distributed almost every South American continent, including Brazil. Coati is popularly known as coati, quati, quati-mundéo and quati of stick (terminology attributed with the shape of its nose similar to a trumpet), which belongs the carnivorous order and Procyonidae family. The Nasua gender comprises two species, Nasua nasua and Nasua narica, however only Nasua nasua occurs in Brazil, in the cerrado biome. The present work aimed an anatomical and comparative study of abdominal aorta to verify the structural organization of this vessel on the body and its adaptations to physiological and evolutionary processes, even as possible inherent adaptations to alimentary and reproductive habit. For this, two male and two female specimens obtained from accidental death on the roadsides of Brazilian Southeast of Goiás was used. The arterial system was dissected and inject with Latex Art Glue, colored with red pigment Wandalar, through the femoral artery. Subsequently was made a fixation with aqueous 10 % formaldehyde solution to conservation. The preparation of anatomical pieces was performed under consecrated techniques in Macroscopic Anatomy. The present study demonstrated that in Coati, the anatomic standard of aorta abdominal part and the respective collateral branch shows a similar template to mammalian animals and the detailed analysis of these abdominal vessels reveals particularities to this specie in small arteries as the Phrenic-Abdominal, Suprarenal and Deep Circumflex Iliac.
