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 follicular phase is to the __________ as the luteal phase is to the secretory phase.

• A. Postovulatory
• B. Menstrual
• C. Proliferative
• D. Ovulatory

Correct answer: C

Rationale: The correct answer is C: Proliferative. The follicular phase corresponds to the proliferative phase during the menstrual cycle, characterized by the development of ovarian follicles. The luteal phase, on the other hand, corresponds to the secretory phase when the endometrium prepares for implantation. Choices A, B, and D are incorrect because they do not accurately reflect the phases being compared in the question.

3. What is the measurement of the breast areola?

• A. 3.5cm
• B. 2.5cm
• C. 4.5cm
• D. 1.5cm

Correct answer: B

Rationale: The correct answer is 2.5 cm. The average measurement of the areola is approximately 2.5 cm. Choices A, C, and D are incorrect as they do not align with the typical measurement of the breast areola.

4. What type of epithelium lines the fallopian tubes?

• A. Ciliated epithelium.
• B. Stratified epithelium.
• C. Columnar epithelium.
• D. Endometrium.

Correct answer: A

Rationale: The correct answer is A: Ciliated epithelium. The fallopian tubes are lined with ciliated epithelium, which helps to move the egg from the ovary to the uterus. Choice B, Stratified epithelium, is incorrect because the fallopian tubes are lined with a single layer of cells. Choice C, Columnar epithelium, is incorrect as it does not accurately describe the lining of the fallopian tubes. Choice D, Endometrium, is incorrect because the endometrium is the inner lining of the uterus, not the fallopian tubes.

5. Approximately how many primordial follicles are present in the cortex of the ovary at birth?

• A. 250,000
• B. 200,000
• C. 150,000
• D. 100,000

Correct answer: A

Rationale: The correct answer is A: 250,000. At birth, there are approximately 250,000 primordial follicles in the cortex of each ovary. These primordial follicles represent the reserve of oocytes that a female will have throughout her reproductive life. Choice B, 200,000, is incorrect as the number is higher. Choices C and D, 150,000 and 100,000 respectively, are also incorrect as they underestimate the actual number of primordial follicles present at birth.
