The pine marten (Martes martes) is a medium sized carnivore rarely found in Iran. The aim of this study was to describe species-specific characteristics of the celiac artery in pine marten. In pine marten examined in this study, it was observed that the celiac artery originated from the ventral aspect of abdominal aorta. The celiac artery was divided into two branches. A thick branch was the common trunk of the splenic and the left gastric arteries, namely the gastrosplenic trunk and the other branch which was thin and longer, namely the hepatic artery. The splenic artery was divided into three branches that supplied the spleen. In the examined pine marten, there were two left gastroepiploic arteries, one originated from the splenic, and the other from the left gastric artery. The hepatic artery was extended to the portal fissure of liver and had five following branches: pancreatic branch, gastroduodenal, right gastric, left hepatic, and right hepatic arteries. The right gastroepiploic artery was originated from the gastroduodenal artery. This is the first report on ramification of the celiac artery in the pine marten

The anatomical studies about the one-humped camels are very little compared to other domestic animal species. The stomach and adjacent organs are blood supplying with the celiac artery. The research on the celiac artery in one-humped camel is very little. The knowledge of branching and variations of the celiac artery is clinically significant, especially in surgical operations. To do this research, five number stomach and adjacent organs of Camelus dromedarius were prepared from the abattoir and then fixed, dissect and analyzed. The celiac artery in the total specimen was originated from the abdominal aorta, separates from the cranial mesenteric artery and divided into three branches, included the hepatic, splenic and left gastric artery. The splenic artery has reached the blood to the spleen only. The left and right ruminal artery were originated together by a common stem from the left gastric artery. The terminal part of the left gastric artery in the lesser curvature of the third compartment (omasum- abomasum) of the camel stomach was divided into two branches, lateral and medial left gastric artery. In the total specimen was recognized one gastroepiploic artery. This artery was originated from the gastroduodenal artery and near the middle part of the greater curvature of the third compartment, ramified into the left and right branches. This study showed that the blood supply of the stomach in one-humped camel is different from other ruminants, and the knowledge of this point is essential in surgical operations.
