**Question:** All of the following are branches of splenic artery, except:
A. Omphalomesenteric Artery
B. Arcuate Artery
C. Pancreaticoduodenal Artery
D. Phrenic Artery
**Core Concept:** The splenic artery (SA) is a branch of the celiac trunk (CT) and supplies blood to the spleen and parts of the gastrointestinal tract. It has several branches which include omphalomesenteric artery, arcuate artery, pancreaticoduodenal artery, and phrenic artery.
**Why the Correct Answer is Right:** The correct answer is D, the phrenic artery. The phrenic artery arises from the subclavian artery, not the splenic artery. Unlike the other options, the phrenic artery does not contribute to the blood supply to the spleen or other digestive organs. Instead, it supplies blood to the diaphragm, chest wall muscles, and lungs.
**Why Each Wrong Option is Incorrect:**
A. Omphalomesenteric Artery: Correct - This artery arises from the splenic artery and supplies blood to the duodenum, pancreas, and spleen.
B. Arcuate Artery: Correct - The arcuate artery is a branch of the splenic artery and supplies blood to the duodenum, particularly the arcuate forks.
C. Pancreaticoduodenal Artery: Correct - This artery is a branch of the splenic artery and supplies blood to the duodenum, head of the pancreas, and the spleen.
**Clinical Pearl:** The splenic artery branches into several arteries that supply blood to various organs. Understanding the anatomy and function of these branches is crucial for diagnosing and treating gastrointestinal and splenic-related conditions accurately. For example, an occluded splenic artery may lead to abdominal pain and splenomegaly, while a dissection of the splenic artery can cause severe abdominal pain and potentially rupture.
