1. 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.

2. The Wolffian duct is also known as ____________.

• A. Mesonephric duct
• B. Ejaculatory duct
• C. Major sublingual duct
• D. Cystic duct

Correct answer: A

Rationale: The correct answer is A: Mesonephric duct. The Wolffian duct is indeed also known as the mesonephric duct. This duct plays a vital role in the development of the male reproductive system by carrying sperm from the epididymis to the ejaculatory duct. Choice B, Ejaculatory duct, is incorrect as it refers to a different duct responsible for transporting semen from the vas deferens. Choices C and D, Major sublingual duct and Cystic duct, are unrelated to the Wolffian duct and are not correct answers in this context.

3. Which statement accurately describes the female pelvis?

• A. Gynaecoid pelvis has a wedge-shaped inlet
• B. Platypelloid pelvis has an oval inlet
• C. Anthropoid pelvis has a long narrow oval inlet
• D. Android pelvis is wedge-shaped

Correct answer: B

Rationale: The correct answer is B because the Platypelloid pelvis indeed has an oval inlet. Gynaecoid pelvis, not mentioned in the choices, has a round inlet. Anthropoid pelvis has a long, narrow oval inlet, which makes choice C incorrect. Choice D is incorrect as the Android pelvis is actually heart-shaped with a narrowed inlet.

4. 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.

5. 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.
