1. How does human sperm move?

• A. Flagella
• B. Cilia
• C. Neutrophils
• D. None of the above

Correct answer: A

Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.

2. What forms the vaginal lining?

• A. Squamous epithelium
• B. Stratified epithelium
• C. Vascular connective tissue
• D. Muscle coat

Correct answer: A

Rationale: The vaginal lining is primarily formed by squamous epithelium. Squamous epithelium is the correct answer because it is the type of epithelium that lines the vaginal canal. Stratified epithelium consists of multiple layers and is not the primary type found in the vaginal lining. Vascular connective tissue and muscle coat are not the main components of the vaginal lining, making them incorrect choices.

3. 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.

4. What is an organelle that helps the sperm to penetrate the ovum?

• A. Acrosome
• B. Zona pellucida
• C. Megalis
• D. None of the above

Correct answer: A

Rationale: The correct answer is Acrosome. The acrosome is an organelle located at the head of a sperm cell and contains enzymes that aid in the penetration of the ovum during fertilization. The Zona pellucida is a glycoprotein membrane surrounding the ovum, not an organelle. Megalis is not a relevant organelle in this context. Therefore, the correct choice is A, Acrosome.

5. What is Carboprost used for?

• A. Affects milk production.
• B. Relieve constriction ring.
• C. Management of post-partum haemorrhage.
• D. Induce labor.

Correct answer: C

Rationale: Carboprost is used in the management of post-partum haemorrhage. This medication helps to reduce excessive bleeding after childbirth. Choices A, B, and D are incorrect. Carboprost does not affect milk production, relieve constriction ring, or induce labor.
