| Popis: | This research was performed aiming to describe the origin and the distribution of the celiac artery in 30 Saffron finches (Sicalis flaveola), through the completion of their circulatory system with an aqueous solution of colored latex, followed by fixation in formol for later dissection of the collateral branches. The celiac artery originated from the descending branch of the aorta, representing its first visceral branch, and was directed to the right antimere of the coelomic cavity. After issuance of the proventricular dorsal artery and the splenic artery, the celiac bifurcated in left and right branches: In all observed finches the left branch originated the proventricular ventral artery, from its left side, and the gastroduodenal and ventral gastric arteries from its right side, in order to continue as the left gastric artery characterizing it as a terminal branch; from its right side, the right branch issued, as first collateral, the right hepatic artery in all observed birds, to originate, from its opposite side, the right gastric and ileal, immediately continuing as pancreaticoduodenal, its terminal branch. From this study, we concluded that the Saffron finch follows the same pattern regarding the origin and distribution of the celiac artery proposed for birds of the genus Gallus, Anas, Columba, Crax, Mitu, and Amazona. Keywords: celiac artery; distribution; origin; Saffron finch; Sicalis flaveola. |
