Understanding the Uterus and Female External Genitalia
The correct answer to the question is option 'A'. Let's delve into why this statement is incorrect.
Detailed Explanation of Option A
- The endometrium is actually the innermost layer of the uterine wall, not the middle layer.
- It is composed of a lining that thickens and sheds during the menstrual cycle, undergoing cyclical changes due to hormonal influences.
Breakdown of Other Options
Option B: Uterine Support
- The uterus is indeed supported by various ligaments that connect it to the pelvic walls.
- These include the broad ligaments, round ligaments, and uterosacral ligaments, which play crucial roles in maintaining its position.
Option C: Myometrium Function
- The myometrium, which is the middle layer of the uterine wall, is responsible for the strong contractions during childbirth.
- This layer consists of smooth muscle that contracts rhythmically to help expel the baby during delivery.
Option D: Labia Majora Description
- The labia majora are indeed fleshy folds of tissue that encase and protect the vaginal opening.
- They are part of the vulva, which is the external structure of the female genitalia.

In summary, option 'A' is incorrect because it misidentifies the endometrium as the middle layer of the uterine wall, whereas it is the innermost layer. Understanding the anatomy of the uterus and female external genitalia is crucial for comprehending female reproductive health.
