1. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:

• A. Zygote
• B. Blastomere
• C. Morula
• D. Blastocyst

Correct answer: C

Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'

2. How do contraceptive oral pills help in birth control?

• A. Preventing ovulation
• B. Killing ova
• C. Killing sperms
• D. More than one of the above

Correct answer: A

Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.

3. 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.

4. Which of the following is a symptom of menopause?

• A. Bleeding per vagina
• B. Sleeping all the time
• C. Insomnia
• D. Increased concentration

Correct answer: C

Rationale: Insomnia is a common symptom of menopause. During menopause, hormonal changes can lead to sleep disturbances, including difficulty falling asleep or staying asleep. Choice A, 'Bleeding per vagina,' is not a typical symptom of menopause but should prompt further evaluation. Choice B, 'Sleeping all the time,' is not a common symptom of menopause; in fact, insomnia, rather than excessive sleep, is more prevalent. Choice D, 'Increased concentration,' is not a symptom of menopause; cognitive changes like forgetfulness or difficulty concentrating may occur, but increased concentration is not a typical manifestation.

5. 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.
