Vascular anatomy of the Phrynops geofroanus. Aorta artery study.

Abstract

Study the behave of the artery aorta, to focus its origin, trajectory, and destiny of its ramifications. Was used five exemplars of Phrynops geofroanus, males and females, adults, from the Uberabinha river, Uberlândia-MG with the scientific fishing license category Dn- 163E DPB/IEF. Was tube the common carotid arteries through which we introduce a physiological solution to remove obstruction from the vascular system, than we inject solution of Neoprene Latex “450” colored. Was fixating the material in solution of Formaldehyde 10% for a period of 96 hours. After this, loose the skull from its insertions, showing the viscera, and individualizing the artery aorta. Were observed that the right and left aortic arcs unite in a point after the origin in the heart. The left aortic arch send the gastric artery, that arise cranial to the point of union of the aortic arcs. It still arises a celiac artery, that provides the cranial and caudal pancreaticduodenal arteries and the cranial and caudal mesenteric arteries. Right after, the trunk formed by the union of the two aortic arcs, is denominated the artery aorta and from it originates the renal arteries, epigastrics, common iliacs and the caudal artery, that is a thin segment of the final portion of the aorta. The aortic right arc does not emit any branch before its union with the left aortic arc, so the main visceral branches comes from the left aortic arc or directly from the aorta artery.
