Comparative Anatomy of Abdominal Aorta in Coati (Nasua nasua)

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.

Origin and main ramifications of coeliac artery in Cerdocyon thous

“…In the wild canid L. gymnocercus, the predominant skeletopy of the CA was at the level of the 2 nd lumbar vertebra, varying cranially to the 1 st lumbar [22], similar to the results obtained in the sampling of C. thous in this research. In other carnivores, including C. familiaris and Felis catus as well as wild canids Vulpes vulpes and procyonid Nasua nasua, the skeletopy was at the level of the first lumbar [1,5,12,33].…”

“…Furthermore, anatomy, one of the oldest biomedical sciences, is a crucial tool for resolving issues regarding the biology and evolution of species, especially concerning interactions involving the habitat environment, feeding, and reproductive adaptations. In addition, the morphology of anatomical structures reveals the natural history of a species (1) .…”

“…Além disso, a anatomia, uma das ciências biomédicas mais antigas, é uma ferramenta crucial para a resolução de questões relacionadas à biologia e evolução das espécies, especialmente no que diz respeito às interações que envolvem o ambiente do habitat, alimentação e adaptações reprodutivas.
