1. What is the triangular space lying between the vaginal and rectal canals?

A. Pelvic floor
B. Perineum
C. Vestibule
D. Perineal body

Correct answer: B

Rationale: The correct answer is B: Perineum. The perineum is the triangular space located between the vaginal and rectal canals. It is a region containing various muscles, nerves, and blood vessels that support the pelvic floor. Choice A, Pelvic floor, refers to the structure supporting the organs in the pelvic cavity, not the space between the vaginal and rectal canals. Choice C, Vestibule, is the space within the labia minora containing the openings of the urethra and vagina, not the area between the vaginal and rectal canals. Choice D, Perineal body, is a fibromuscular mass in the perineum area but not the space between the vaginal and rectal canals.

2. Which one is not a barrier method for birth control?

A. Diaphragms
B. Cervical caps
C. Vaults
D. Intrauterine Devices (IUDs)

Correct answer: D

Rationale: The correct answer is D, Intrauterine Devices (IUDs). Barrier methods of birth control physically block sperm from reaching the egg. Diaphragms, cervical caps, and vaults are examples of barrier methods as they create a barrier that prevents sperm from reaching the cervix. In contrast, IUDs work by altering the cervical mucus and uterine lining, making it difficult for sperm to reach the egg, but they do not physically block sperm like barrier methods do.

3. What is the content of the acrosome?

A. Lipids
B. Hormones
C. Digestive enzymes
D. None of the above

Correct answer: C

Rationale: The correct answer is C: Digestive enzymes. The acrosome is a structure found in sperm cells that contains enzymes used to penetrate the egg during fertilization. Choice A (Lipids) and Choice B (Hormones) are incorrect as the primary content of the acrosome is digestive enzymes, not lipids or hormones. Choice D (None of the above) is incorrect as the acrosome does contain a specific substance, which are digestive enzymes.

4. Which of the following structures is responsible for the production of sperm?

A. Epididymis
B. Seminal vesicles
C. Testes
D. Prostate gland

Correct answer: C

Rationale: The testes are the male reproductive organs responsible for the production of sperm through a process called spermatogenesis. The epididymis is a structure where sperm mature and are stored temporarily. Seminal vesicles produce a significant portion of the fluid that ultimately becomes semen, but they do not produce sperm. The prostate gland contributes additional fluid to semen but does not produce sperm. Therefore, the correct answer is the testes.

5. What is the most common cause of abortion in Zambia?

A. Malaria.
B. Tuberculosis.
C. HIV.
D. Ascariasis.

Correct answer: A

Rationale: The correct answer is A: Malaria. Malaria is a prevalent cause of abortion in Zambia due to its impact on maternal health. Malaria infection during pregnancy can lead to severe complications, including miscarriage. Choices B, C, and D are incorrect because while Tuberculosis, HIV, and Ascariasis are significant health issues, they are not the commonest cause of abortion in Zambia as Malaria.
