In which of the following vessels transverse mesocolon seen ?
**Core Concept**
Transverse mesocolon is a peritoneal fold that connects the transverse colon to the posterior wall of the abdomen. It is a vital structure for the support and positioning of the transverse colon.
**Why the Correct Answer is Right**
The transverse mesocolon is seen in the transverse mesocolic vessels, which are a collection of blood vessels that supply the transverse colon. These vessels include the middle colic artery and vein, which are branches of the superior mesenteric artery and vein. The transverse mesocolon also contains the inferior mesenteric vein, which drains into the splenic vein. The vessels within the transverse mesocolon are responsible for the blood supply and drainage of the transverse colon.
**Why Each Wrong Option is Incorrect**
**Option A:** The greater omentum is a large peritoneal fold that hangs down from the greater curvature of the stomach, but it is not associated with the transverse mesocolon.
**Option B:** The lesser omentum is a peritoneal fold that connects the liver to the lesser curvature of the stomach, and it does not contain the vessels of the transverse mesocolon.
**Option C:** The sigmoid mesocolon is a peritoneal fold that connects the sigmoid colon to the posterior wall of the abdomen, but it is not associated with the transverse mesocolon.
**Clinical Pearl / High-Yield Fact**
The transverse mesocolon is a common site for the formation of a mesenteric hematoma, which can be a complication of trauma or surgery.
**Correct Answer:** C.
