## **Core Concept**
The support of the uterus is primarily maintained by a combination of ligaments, muscles, and fascial layers. The main structures responsible for uterine support include the **cardinal ligaments**, **uterosacral ligaments**, **round ligaments of the uterus**, and the **levator ani muscles**. These structures work together to maintain the anatomical position of the uterus.

## **Why the Correct Answer is Right**
The correct answer, , involves the **cardinal ligaments** (also known as Mackenrodt's ligaments or transverse cervical ligaments). These ligaments are crucial for uterine support as they provide lateral support to the cervix and vagina, thereby indirectly supporting the uterus. They are located at the base of the broad ligament and attach to the lateral aspects of the cervix and the lateral pelvic wall. The cardinal ligaments play a significant role in maintaining the pelvic organ's position and preventing prolapse.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that uterine prolapse or pelvic organ prolapse can occur due to the weakening of these supportive structures, often as a result of childbirth, menopause, or conditions that increase abdominal pressure. Understanding the role of the cardinal ligaments and other supportive structures is essential for the management and surgical treatment of uterine prolapse.
