Which artery is the principal artery of stomach?
The stomach is supplied by a rich system of arteries derived from the celiac trunk, the first major visceral branch of the abdominal aorta. The lesser curvature of the stomach is supplied by the left and right gastric artery, which are branches of the celiac trunk and the common hepatic artery respectively.
Which of these organs is retroperitoneal in location?
Anatomy. The retroperitoneal space is bounded by the posterior parietal peritoneum anteriorly and the lumbar spine posteriorly. The retroperitoneal space contains the kidneys, adrenal glands, pancreas, nerve roots, lymph nodes, abdominal aorta, and inferior vena cava.
What artery runs posterior to the stomach?
The splenic artery is contained within the splenorenal ligament and runs posterior to the stomach and along the superior pancreas.
Why kidneys are called retroperitoneal?
The kidneys are considered “retroperitoneal” organs, which means they sit behind a lining in the abdominal cavity, unlike all other abdominal organs.

What is the difference between the inferior epigastric and obturator?
The pubic branch of the inferior epigastric artery is then considered as the site of origin of the obturator artery, and is referred to as the aberrant or replaced obturator artery. The inferior epigastric may also be doubled. Relatively often, the artery can be referred to as the deep inferior epigastric artery when a superficial one is present.
What causes the inferior epigastric to be doubled?
The inferior epigastric may be doubled. The inferior epigastric may arise from, or conversely, give rise to the obturator artery. This variation is due to the anastomosis of the epigastric and obturator through their pubic branches.
What artery anastomoses with the superior epigastric artery?
It anastomoses with the superior epigastric artery. Along its course, it is accompanied by a similarly named vein, the inferior epigastric vein. These epigastric vessels form the lateral border of Hesselbach’s triangle, which outlines the area through which direct inguinal hernias protrude.
