1. What is the role of the corpus luteum during the menstrual cycle?

• A. The corpus luteum produces estrogen to maintain the endometrium.
• B. The corpus luteum produces progesterone to maintain the endometrium.
• C. The corpus luteum produces testosterone to inhibit ovulation.
• D. The corpus luteum has no significant role during the menstrual cycle.

Correct answer: B

Rationale: The correct answer is B: The corpus luteum produces progesterone to maintain the endometrium during the menstrual cycle. This hormone helps prepare the uterine lining for implantation in case fertilization occurs. Choice A is incorrect because estrogen is mainly produced by the developing follicles in the ovaries. Choice C is incorrect as testosterone is produced in smaller amounts by the ovaries and adrenal glands but does not play a significant role in maintaining the endometrium. Choice D is incorrect as the corpus luteum plays a crucial role in producing progesterone to support the endometrium.

2. Which of the following is the description of a normal cervix on speculum examination in a non-pregnant woman of reproductive age?

• A. Bright red mucosa surrounding the cervical os, in turn surrounded by smooth, pink mucosa
• B. Pink mucosa with multiple small, fluid-filled protrusions
• C. Pink, glistening, smooth mucosa of the exocervix, with a small round or fish-mouthed cervical os
• D. Smooth, pink mucosa and a small, fleshy protrusion through the cervical os

Correct answer: C

Rationale: The correct description of a normal cervix on speculum examination in a non-pregnant woman of reproductive age is pink, glistening, smooth mucosa of the exocervix, with a small round or fish-mouthed cervical os. This appearance is characteristic of a healthy cervix. Choice A is incorrect as a bright red mucosa is not normal. Choice B is incorrect as multiple small, fluid-filled protrusions suggest a different condition. Choice D is incorrect as a fleshy protrusion through the cervical os is abnormal.

3. What is the typical measurement of the anterior wall of the vaginal canal?

• A. 10 cm
• B. 11 cm
• C. 11.5 cm
• D. 7.5 cm

Correct answer: D

Rationale: The typical measurement of the anterior wall of the vaginal canal is 7.5 cm. This measurement is anatomically accurate, making choice D the correct answer. Choices A, B, and C provide measurements that are larger than the typical measurement of the anterior wall of the vaginal canal and are therefore incorrect.

4. What type of epithelium lines the urinary bladder?

• A. Transitional epithelium.
• B. Stratified epithelium.
• C. Glandular tissue.
• D. Endometrium.

Correct answer: A

Rationale: The correct answer is A: Transitional epithelium. The urinary bladder is lined with transitional epithelium, a specialized type of epithelial tissue that can stretch and recoil to accommodate changes in volume as the bladder fills and empties. Stratified epithelium (choice B) is not the main lining of the urinary bladder and is found in other areas like the skin. Glandular tissue (choice C) is responsible for producing secretions and is not typically found lining the urinary bladder. Endometrium (choice D) is the inner lining of the uterus and is not present in the urinary bladder.

5. During the menstrual cycle, which hormone maintains the corpus luteum?

• A. Luteinizing hormone
• B. Follicle-stimulating hormone
• C. Progesterone
• D. Relaxin

Correct answer: A

Rationale: During the menstrual cycle, luteinizing hormone maintains the corpus luteum. The correct answer is A. Luteinizing hormone stimulates the corpus luteum to produce progesterone. Choice B, Follicle-stimulating hormone, is involved in stimulating the growth of follicles in the ovaries. Choice C, Progesterone, is produced by the corpus luteum and plays a role in preparing the endometrium for implantation. Choice D, Relaxin, is involved in processes such as softening the cervix and ligaments during pregnancy, but it is not responsible for maintaining the corpus luteum.
