The aim of this study was to investigate the course and distribution of the celiac artery in Hooded crows and to extend our knowledge on the captured crows. Scarce information in the field of veterinary comparative anatomy and the available literature on the celiac artery and its distribution is provided. So, the present study tried to declare the confusion about the course and distribution of the celiac artery in the Hooded crows. Therefore, 10 apparently healthy Hooded crows of different ages and sexes were captured. The birds were anaesthetized by IM injection of 0.5 cc of 2% xylazine HCL (3 mg/kg). Colored gum milk latex (60%) was then injected through the descending aorta. Then, specimens were subjected to fine dissection to demonstrate the origin, course and distribution of the celiac artery. The celiac artery erupted laterally from the right face of the descending aorta opposite to the distance between the 5th and 6th vertebral rib, on a level with the junction of the esophagus and the proventriculus. It proceeded ventrally and slight caudally, where it gave off the esophageal artery after, 5 cm from its origin, the dorsal proventricular artery, splinc arteries and at the middle of spleen then bifurcated into left and right branches. The left branch of the celiac artery gave rise to right hepatic artery, ventral proventricular artery, pyloric branches, ventral gastric artery and then continued as the A. gastrica sinistra. The right branch of the celiac artery released the caudal group of splenic arteries, A. gastrica dextra, then continued as A. pancreaticoduodenalis.
