Reproductive System Exam Quizlet
1. What forms the vaginal lining?
- A. Squamous epithelium
- B. Stratified epithelium
- C. Vascular connective tissue
- D. Muscle coat
Correct answer: A
Rationale: The vaginal lining is primarily formed by squamous epithelium. Squamous epithelium is the correct answer because it is the type of epithelium that lines the vaginal canal. Stratified epithelium consists of multiple layers and is not the primary type found in the vaginal lining. Vascular connective tissue and muscle coat are not the main components of the vaginal lining, making them incorrect choices.
2. Which one of the following is not a stage in the ovarian cycle of the menstrual cycle?
- A. Recruitment of Graafian follicle
- B. Selection of dominant follicle
- C. Luteal phase
- D. Formation of corpus luteum
Correct answer: A
Rationale: The correct answer is A. The recruitment of the Graafian follicle is indeed a stage in the ovarian cycle. During the ovarian cycle, the primary follicles are recruited to develop further, leading to the formation of the Graafian follicle. The selection of the dominant follicle, luteal phase, and formation of the corpus luteum are other essential stages in the ovarian cycle. Therefore, option A is not correct as it is a crucial phase in the process of ovulation and fertilization.
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. The upper folds of the labia minora surround the clitoris and unite to form the:
- A. Frenulum
- B. Prepuce
- C. Fourchette
- D. Vestibule
Correct answer: B
Rationale: The correct answer is B: Prepuce. The upper folds of the labia minora surround the clitoris and unite to form the prepuce, which is a hood-like structure protecting the clitoris. The frenulum (choice A) is a small fold of tissue under the tongue or upper lip, not related to the female genitalia. The fourchette (choice C) refers to the area where the labia minora meet at the posterior end of the vulva, not involving the clitoris. The vestibule (choice D) is the space between the labia minora containing the vaginal and urethral openings, not directly formed by the upper folds of the labia minora.
5. What is the function of luteinizing hormone?
- A. Maintains the corpus luteum
- B. Ripens the Graafian follicle
- C. Prepares the breasts for lactation
- D. Produces regrowth of the endometrium
Correct answer: A
Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.
