Which of the following aery gives rise to posterior gastric aery
**Core Concept**
The posterior gastric artery is one of the branches that supply blood to the stomach. It is a small artery that arises from a larger vessel that supplies the abdominal cavity.
**Why the Correct Answer is Right**
The posterior gastric artery arises from the splenic artery, which is a branch of the celiac trunk. The celiac trunk is a major artery that arises from the abdominal aorta and supplies blood to the upper abdominal organs, including the stomach, liver, and pancreas. The splenic artery then divides into several branches, including the short gastric arteries and the left gastroepiploic artery, which supply the stomach and spleen. The posterior gastric artery is one of the smaller branches of the splenic artery that supplies the posterior aspect of the stomach.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the right gastric artery is a branch of the common hepatic artery, not the splenic artery.
* **Option B:** This option is incorrect because the left gastroepiploic artery is a branch of the splenic artery, but it supplies the greater curvature of the stomach, not the posterior aspect.
* **Option D:** This option is incorrect because the right gastroepiploic artery is a branch of the gastroduodenal artery, not the splenic artery.
**Clinical Pearl / High-Yield Fact**
The posterior gastric artery is a small but important branch of the splenic artery that supplies the posterior aspect of the stomach. This artery is at risk during surgical procedures that involve the stomach and spleen, such as splenectomy or gastric resection.
**Correct Answer: C. The splenic artery.**
