1. Which of the following is a function of the placenta?

• A. The placenta secretes insulin.
• B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
• C. The placenta provides immunological protection to the fetus.
• D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

2. Which one of the following is not a stage in the ovarian cycle of the menstrual cycle?

• A. Recruitment of Graafian follicle
• B. Selection of dominant follicle
• C. Luteal phase
• D. Formation of corpus luteum

Correct answer: A

Rationale: The correct answer is A. The recruitment of the Graafian follicle is indeed a stage in the ovarian cycle. During the ovarian cycle, the primary follicles are recruited to develop further, leading to the formation of the Graafian follicle. The selection of the dominant follicle, luteal phase, and formation of the corpus luteum are other essential stages in the ovarian cycle. Therefore, option A is not correct as it is a crucial phase in the process of ovulation and fertilization.

3. 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.

4. Which of the following hormones promotes endometrial growth?

• A. LH
• B. FSH
• C. Estrogen
• D. Progesterone

Correct answer: C

Rationale: Estrogen is the hormone responsible for promoting endometrial growth. Estrogen helps thicken the endometrium during the menstrual cycle in preparation for implantation. LH (Choice A) and FSH (Choice B) are involved in regulating the menstrual cycle but do not directly promote endometrial growth. Progesterone (Choice D) is important for maintaining the endometrium after ovulation but is not the primary hormone responsible for promoting its growth.

5. 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.
