_______ is a lytic enzyme released by the sperm.
- A. Hyaluronidase

Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

The endometrial tissue of the cervix is arranged in folds known as:
- A. Racemose glands
- B. Rugae
- C. Arbor vitae
- D. Peritoneum
Correct Answer: B
Rationale: The endometrial tissue of the cervix is arranged in folds known as rugae, not Arbor vitae.

Racemose glands refer to branched compound glands, Arbor vitae is the tree-like appearance of the cerebellum, and Peritoneum is the serous membrane lining the abdominal cavity.
Menopausal women require a diet rich in calcium to prevent osteoporosis. Which one of the following is a source of calcium?
- A. Spinach
- B. Cabbage
- C. Carrots
- D. Rape
Correct Answer: A
Rationale: Corrected Rationale: Spinach is a good source of calcium, which is crucial for preventing osteoporosis in menopausal women. Spinach is a leafy green vegetable high in calcium content. While cabbage, carrots, and rape are nutritious, they do not provide as much calcium as spinach does. Therefore, spinach is the correct choice for menopausal women looking to increase their calcium intake.
Which space is present between the bladder and the uterus?
- A. Vesico-uterine pouch
- B. Pubovesical pouch
- C. Retro-uterine pouch
- D. Recto-uterine pouch
Correct Answer: A
Rationale: The correct answer is the vesico-uterine pouch. This space is specifically located between the bladder and the uterus. The pubovesical pouch is incorrect as it refers to the space between the pubic bone and the bladder. The retro-uterine pouch, also known as the pouch of Douglas, is located between the uterus and rectum. The recto-uterine pouch is not a recognized anatomical term, making it an incorrect choice.
What prompted Zambia to implement family planning services?
- A. The nation started to experience the effects of rapid population growth on the economy and individual welfare.
- B. Donors provided free family planning pills.
- C. Mothers were delivering twice a year.
- D. There were too many abortions.
Correct Answer: A
Rationale: The correct answer is A. Rapid population growth's impact on the economy and individual welfare prompted Zambia to implement family planning services. This is because a rapidly growing population can strain resources, lead to unemployment, poverty, and inadequate access to healthcare. Choice B is incorrect because the provision of free family planning pills by donors may have been a subsequent intervention rather than the initial reason for implementing family planning services. Choice C is irrelevant as the frequency of deliveries by mothers does not directly relate to the implementation of family planning services. Choice D is also incorrect as high abortion rates may be a consequence of inadequate family planning services rather than the reason for their implementation.
