Resumo: |
This study aims to analyze the morphology of the celiac trunk of sloth. To this end, four adult sloths, three females and one male, the Bradypus variegatus species belonging to the area of Anatomy, Department of Animal Morphology and Physiology, Federal Rural University of Pernambuco (DMFA / UFRPE) were used. The four specimens were obtained after natural death and formolized injected with Neoprene latex 650 (DuPont®), with red from cannulation of the common carotid artery pigment. Later, they were dissected for analysis of stem celiac, which was measured. Based on morphometric data obtained at a range of 0.06 to 0,46mm the trunk diameter of 0.04 to 1.3 mm for the length of the trunk and 2.88 to 5.7mm distance between trunk and the diaphragm. Observing the wide variation in the branching of the aorta to the celiac trunk-level, the cranial mesenteric artery or the celiac-mesenteric trunk. Since, each animal of the various classifications of domestic to wild animals have peculiar anatomical features. Is therefore necessary to study and compared between species in order to detail their similarities and differences. Notably, the current species of sloth have numerous relatively old anatomical and functional characteristics. Its branching from the aorta can be celiac trunk mesenteric, celiac arteries, and when emerging from the cranial mesenteric aorta on a common core, or they may be derived separately. The celiac and cranial mesenteric artery abdominal blood vessels are of great importance in terms of vascularization as supplying important viscera, liver, stomach, intestines, spleen and pancreas, its branches, so can be left gastric artery, hepatic and splenic (or spleen), typically having other types of branching within the same species. From the point of view phylogenetic these characteristics are quite specialized and standards that differ from those usually found in most mammals. However, the consultations revealed a deficiency in literature studies about morphology in these animals, especially in relation to the cardiovascular system. In view of this, the characterization and detail of one of the parts of this vast system contributes significantly in the understanding of anatomy and physiological functioning of organs irrigated by the celiac trunk, the sloth. |
