1. Which structure maintains the uterus in an anteverted and anteflexed position?

• A. Round ligaments
• B. Broad ligaments
• C. Cardinal ligaments
• D. Pubocervical ligaments

Correct answer: A

Rationale: The correct answer is the Round ligaments. The round ligaments are responsible for maintaining the uterus in an anteverted and anteflexed position. These ligaments attach from the sides of the uterus and extend through the inguinal canal to the labia majora. The other choices, Broad ligaments, Cardinal ligaments, and Pubocervical ligaments, have different functions and attachments within the pelvis. Broad ligaments are a double layer of peritoneum that encloses the uterus and supports the uterine tubes. Cardinal ligaments provide support to the cervix and upper vagina. Pubocervical ligaments support the cervix and bladder.

2. What term is used to refer to the fertilized ovum?

• A. Zygote
• B. Embryo
• C. Foetus
• D. Pregnancy

Correct answer: A

Rationale: The correct answer is A, Zygote. A zygote is formed when a sperm cell fertilizes an egg cell. It is the initial stage of prenatal development. Choice B, Embryo, refers to the stage of prenatal development after the zygote and before the foetus. Choice C, Foetus, is the stage of prenatal development after the embryo. Choice D, Pregnancy, is a broader term referring to the condition of having a developing baby in the uterus.

3. What phase corresponds with the luteal phase?

• A. Menstrual phase
• B. Follicular phase
• C. Secretory phase
• D. Menstrual phase

Correct answer: C

Rationale: The luteal phase corresponds with the secretory phase. During the menstrual cycle, the luteal phase follows ovulation and is characterized by the development of the corpus luteum, secreting progesterone to prepare the endometrium for a potential pregnancy. The other choices, menstrual phase (A), follicular phase (B), and the repeated choice of menstrual phase (D) do not align with the luteal phase and its functions.

4. Where does the ovum receive the sperm?

• A. Animal pole
• B. Vegetal pole
• C. Zona pellucida
• D. None of the above

Correct answer: C

Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.

5. 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.
