**Core Concept**
The internal iliac artery, also known as the hypogastric artery, is a major branch of the common iliac artery that supplies blood to the pelvic region. It is a key vessel in the autonomic nervous system, playing a crucial role in regulating blood pressure and providing oxygenated blood to various pelvic organs.

**Why the Correct Answer is Right**
The internal iliac artery gives rise to several important branches, including the anterior division, which supplies the pelvic walls, external genitalia, and abdominal walls. The posterior division, on the other hand, supplies the pelvic viscera, including the rectum, bladder, and reproductive organs. The internal iliac artery also provides a significant portion of the blood supply to the pelvic organs, making it a vital vessel in the pelvic region.

**Why Each Wrong Option is Incorrect**
**Option A:** Middle meningeal artery - This artery is a branch of the maxillary artery, which is itself a branch of the external carotid artery, and is not related to the internal iliac artery.
**Option B:** Middle colic artery - This artery is a branch of the superior mesenteric artery, which supplies the midgut, and is not related to the internal iliac artery.
**Option C:** Superior mesenteric artery - This artery is a major branch of the abdominal aorta, supplying the midgut, and is not related to the internal iliac artery.

**Clinical Pearl / High-Yield Fact**
The internal iliac artery is a common site for embolic events, particularly in patients with atrial fibrillation or other cardiac conditions that increase the risk of thromboembolism.

**Correct Answer: C. Superior gluteal artery.**
