1. What is the role of relaxin hormone?

• A. Relaxation of the symphysis pubis.
• B. Stimulation of milk production.
• C. Stimulating the development of the nipple and duct system in the breast.
• D. None of the above.

Correct answer: A

Rationale: The correct answer is A: Relaxation of the symphysis pubis. Relaxin hormone is responsible for loosening the ligaments in the pelvic area, particularly the symphysis pubis, to prepare for childbirth. Choice B, stimulation of milk production, is incorrect as this is primarily regulated by prolactin. Choice C, stimulating the development of the nipple and duct system in the breast, is incorrect as this is mainly influenced by estrogen and progesterone during pregnancy. Therefore, the correct role of relaxin hormone is the relaxation of the symphysis pubis.

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. What is the triangular space lying between the vaginal and rectal canals?

• A. Pelvic floor
• B. Perineum
• C. Vestibule
• D. Perineal body

Correct answer: B

Rationale: The correct answer is B: Perineum. The perineum is the triangular space located between the vaginal and rectal canals. It is a region containing various muscles, nerves, and blood vessels that support the pelvic floor. Choice A, Pelvic floor, refers to the structure supporting the organs in the pelvic cavity, not the space between the vaginal and rectal canals. Choice C, Vestibule, is the space within the labia minora containing the openings of the urethra and vagina, not the area between the vaginal and rectal canals. Choice D, Perineal body, is a fibromuscular mass in the perineum area but not the space between the vaginal and rectal canals.

4. What structure lies posterior to the vagina?

• A. Pouch of Douglas
• B. Rectum
• C. Perineal body
• D. Structures of the vulva

Correct answer: B

Rationale: The correct answer is B: Rectum. The rectum is located posterior to the vagina in the pelvic cavity. The Pouch of Douglas (choice A) is a peritoneal pouch located between the rectum and the uterus. The perineal body (choice C) is a fibrous structure located between the vagina and the anus. Structures of the vulva (choice D) are external genital structures surrounding the vaginal opening, not posterior to the vagina.

5. Which structure maintains the uterus in an anteverted and anteflexed position?

• A. Round ligaments
• B. Broad ligaments
• C. Cardinal ligaments
• D. Pubocervical ligaments

Correct answer: A

Rationale: The correct answer is the Round ligaments. The round ligaments are responsible for maintaining the uterus in an anteverted and anteflexed position. These ligaments attach from the sides of the uterus and extend through the inguinal canal to the labia majora. The other choices, Broad ligaments, Cardinal ligaments, and Pubocervical ligaments, have different functions and attachments within the pelvis. Broad ligaments are a double layer of peritoneum that encloses the uterus and supports the uterine tubes. Cardinal ligaments provide support to the cervix and upper vagina. Pubocervical ligaments support the cervix and bladder.
