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. Which of the following are layers of the anterior abdominal wall?

• A. Linear albicantes
• B. Superficial fascia
• C. Visceral peritoneum
• D. Fascia transversalis

Correct answer: A

Rationale: The correct answer is A: Linear albicantes and B: Superficial fascia. Linear albicantes are stretch marks, and the superficial fascia is one of the layers of the anterior abdominal wall. Choices C and D, Visceral peritoneum and Fascia transversalis, respectively, are not layers of the anterior abdominal wall. The visceral peritoneum is a membrane covering the abdominal organs, and the fascia transversalis is a layer deep to the transversus abdominis muscle.

3. What does the umbilical cord contain?

• A. Pluripotent stem cells
• B. Cord blood stem cells
• C. Blood stem cells
• D. None of the above

Correct answer: B

Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.

4. Which hormone regulates the production of milk after childbirth?

• A. Prolactin
• B. Oxytocin
• C. Estrogen
• D. Progesterone

Correct answer: A

Rationale: The correct answer is Prolactin. Prolactin is the hormone responsible for regulating the production of milk after childbirth. It stimulates the mammary glands in the breasts to produce milk. Oxytocin, on the other hand, is responsible for the ejection of milk from the breasts. Estrogen and progesterone play roles in the menstrual cycle and pregnancy but are not directly involved in milk production. Therefore, choices B, C, and D are incorrect.

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.
