Uterine prolapse is caused by stretching of the uterine:

• A. muscle
• B. tendons
• C. ligaments
• D. wall

Answer: (C)

Uterine prolapse occurs when the supportive structures of the uterus become weakened or stretched, allowing the uterus to descend into the vaginal canal. The primary support for the uterus comes from the pelvic floor, specifically the ligaments that anchor it in place. These ligaments include the uterosacral ligaments, cardinal ligaments, and round ligaments, which provide necessary support to maintain the correct anatomical position of the uterus.

When these ligaments stretch or become weakened—due to factors such as childbirth, aging, hormonal changes, or increased abdominal pressure—the uterus may lose its structural integrity, leading to prolapse. This renders the sagging of the uterus into the vagina, and highlights the importance of the ligaments in maintaining pelvic organ support.

The other options, although relevant to the structure of the uterus, do not primarily contribute to its support in the same way ligaments do. The muscle consists of the myometrium, which primarily facilitates contractions during childbirth, while the wall comprises the uterine tissue itself. Tendons are not involved in the support of the uterus in this context. Therefore, the correct answer emphasizes the role of ligaments in uterine support and the development of prolapse when these structures are compromised.
