Which of the following statements is true about the round ligament
**Core Concept**
The round ligament is a fibromuscular band that connects the uterus to the labia majora, playing a crucial role in maintaining uterine position and providing support during pregnancy.
**Why the Correct Answer is Right**
The round ligament is a continuation of the broad ligament, which is a fold of peritoneum that attaches the uterus to the pelvic sidewall. The round ligament consists of smooth muscle and connective tissue, allowing it to contract and provide support to the uterus. During pregnancy, the round ligament stretches to accommodate the growing uterus, but it remains attached to the labia majora, maintaining uterine position.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the round ligament does not provide primary support to the bladder.
**Option B:** This option is incorrect because the round ligament is not a major contributor to uterine blood supply.
**Option C:** This option is incorrect because the round ligament does not have a significant role in uterine contractions during labor.
**Clinical Pearl / High-Yield Fact**
The round ligament is often used as a landmark during gynecologic surgeries, such as hysterectomies, to avoid damaging surrounding structures.
**Correct Answer: C. The round ligament is a fibromuscular band that connects the uterus to the labia majora.**
