Reproductive System Exam Quizlet
1. Which of the following is the most effective method of contraception?
- A. Barrier methods
- B. Hormonal pills
- C. Intrauterine devices (IUDs)
- D. Sterilization
Correct answer: D
Rationale: Sterilization is considered the most effective method of contraception because it permanently prevents pregnancy. Barrier methods, hormonal pills, and IUDs are highly effective as well, but they are reversible methods and may have a higher failure rate compared to sterilization.
2. What is the area of the uterus where the fallopian tubes are inserted known as?
- A. Fundus
- B. Corpus or body
- C. Cavity
- D. Cornua
Correct answer: D
Rationale: The correct answer is D, Cornua. The cornua refers to the upper, horn-like parts of the uterus where the fallopian tubes are inserted. The fundus (choice A) is the rounded top portion of the uterus, the corpus or body (choice B) is the main part of the uterus excluding the cervix and fundus, and the cavity (choice C) refers to the internal space within the uterus. Therefore, choices A, B, and C are incorrect as they do not specifically denote the area where the fallopian tubes are inserted.
3. What is one role of the hormone estrogen?
- A. Stimulates the development of the milk-producing tissue.
- B. Stimulates the production of lactoferrin.
- C. Stimulates the development of the nipple and duct system in the breast.
- D. Stimulates the secretion of relaxin.
Correct answer: A
Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.
4. 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.
5. Which of the following is NOT a phase of the menstrual cycle?
- A. Follicular phase
- B. Ovulatory phase
- C. Luteal phase
- D. Secretory phase
Correct answer: D
Rationale: The secretory phase is not considered a distinct phase of the menstrual cycle; it is actually part of the luteal phase. During the luteal phase, the endometrium thickens due to progesterone secretion, preparing for implantation. The follicular phase is characterized by follicle development, leading to ovulation. The ovulatory phase is when the mature egg is released from the ovary. Therefore, the secretory phase is the correct answer as it is not a standalone phase but a part of the luteal phase.
