Question

Assertion (A): Supravaginal elongation of cervix occurs in uterovaginal prolapse.

Reason (R): There is gaping genital hiatus but the ligamentous support of uterus is strong.

• A. Both A and R are true and R is the correct explanation of A.
• B. Both A and R are true but R is NOT the correct explanation of A.
• C. A is true but R is false.
• D. A is false but R is true.

Hint:

Ask whether prolapse happens because pelvic support is strong or because it has weakened.

Answer 1

The Correct Option is C

This question checks whether prolapse happens because the uterus's support is strong or because it has failed. Let's go through the options.

1. Both true, R explains A: This needs the ligamentous support to be described correctly as strong, which is wrong, so this option is out.
2. Both true, R does not explain A: This also needs R to be true, which it is not.
3. A true, R false: As the uterus descends in prolapse, the supravaginal part of the cervix, above where the vagina attaches, gets pulled and stretched, so it genuinely elongates over time. This makes the assertion true. But prolapse itself is caused by weak, stretched, or torn pelvic supports, the ligaments and muscles that normally hold the uterus up, not by strong support. So calling the ligamentous support strong is incorrect, and the reason is false. This option fits.
4. A false, R true: This fails because supravaginal elongation is a real, accepted feature of prolapse, so A is not false.

The genital hiatus part of the reason is fair, prolapse does widen the vaginal opening, but pairing it with strong ligamentous support flips the actual cause of prolapse on its head.

Let's summarize:

• Supravaginal cervical elongation is a genuine finding in long-standing uterovaginal prolapse.
• Prolapse results from weakened, not strong, ligamentous and muscular support of the uterus.

So A is true but R is false.
