What is the area of the uterus where the fallopian tubes are inserted known as?
- A. Fundus
- B. Corpus or body
- C. Cavity
- D. Cornua
Correct Answer: D
Rationale: The correct answer is D, Cornua. The cornua refers to the upper, horn-like parts of the uterus where the fallopian tubes are inserted. The fundus (choice A) is the rounded top portion of the uterus, the corpus or body (choice B) is the main part of the uterus excluding the cervix and fundus, and the cavity (choice C) refers to the internal space within the uterus. Therefore, choices A, B, and C are incorrect as they do not specifically denote the area where the fallopian tubes are inserted.

Which of the following are examples of external genitalia?
- A. Mons veneris
- B. Labia majora
- C. Vagina
- D. Cervix
Correct Answer: A
Rationale: The correct answer is A: Mons veneris. The mons veneris and labia majora are considered external genitalia as they are visible externally.

What type of epithelium lines the vagina?
- A. Ciliated epithelium.
- B. Squamous epithelium.
- C. Columnar epithelium.
- D. Transitional epithelium.
Correct Answer: B
Rationale: The correct answer is B: Squamous epithelium. The vagina is lined with non-keratinized stratified squamous epithelium. This type of epithelium provides protection against abrasion and pathogens. Choice A, Ciliated epithelium, is incorrect as ciliated epithelium is found in areas like the fallopian tubes to help move the egg towards the uterus. Choice C, Columnar epithelium, is incorrect as columnar epithelium is typically found in areas like the intestines. Choice D, Transitional epithelium, is incorrect as this type of epithelium is found in areas like the urinary bladder.
Polymenorrhoea is defined as:
- A. Menstruation that occurs at an interval less than 35 days
- B. Menstruation that occurs at an interval greater than 35 days
- C. Menstruation that occurs at an interval less than 21 days
- D. Menstruation that occurs at an interval greater than 21 days
Correct Answer: C
Rationale: Polymenorrhoea is defined as menstruation that occurs at intervals shorter than 21 days. Choice A is incorrect because it describes menstruation at intervals less than 35 days. Choice B is incorrect as it describes menstruation at intervals greater than 35 days. Choice D is incorrect as it describes menstruation at intervals greater than 21 days.
What is the role of the corpus luteum during the menstrual cycle?
- A. The corpus luteum produces estrogen to maintain the endometrium.
- B. The corpus luteum produces progesterone to maintain the endometrium.
- C. The corpus luteum produces testosterone to inhibit ovulation.
- D. The corpus luteum has no significant role during the menstrual cycle.
Correct Answer: B
Rationale: The correct answer is B: The corpus luteum produces progesterone to maintain the endometrium during the menstrual cycle. This hormone helps prepare the uterine lining for implantation in case fertilization occurs. Choice A is incorrect because estrogen is mainly produced by the developing follicles in the ovaries. Choice C is incorrect as testosterone is produced in smaller amounts by the ovaries and adrenal glands but does not play a significant role in maintaining the endometrium. Choice D is incorrect as the corpus luteum plays a crucial role in producing progesterone to support the endometrium.
Oligomenorrhea is defined as a cycle longer than:
- A. 28 days
- B. 30 days
- C. 35 days
- D. 40 days
Correct Answer: C
Rationale: Oligomenorrhea is defined as a menstrual cycle longer than 35 days. A cycle of 28 days (Choice A) is within the normal range, and not considered oligomenorrhea. Similarly, 30 days (Choice B) and 40 days (Choice D) are also within the normal range. The correct definition of oligomenorrhea specifically refers to cycles longer than 35 days, making Choice C the correct answer.
