Reproductive System Quizlet Questions
Question 1 of 5
Which is true of prostate cancer?
Correct Answer: D
Rationale: The correct answer is D. Ethnicity is a risk factor for prostate cancer. African American men have a higher risk compared to other ethnicities. This is supported by research and epidemiological studies. Choice A is incorrect as prostate cancer, when detected early, has a high survival rate. Choice B is also incorrect as prostate cancer is one of the most common cancers in men. Choice C is incorrect as having a family history of prostate cancer is a known risk factor.
Question 2 of 5
A female athlete who took testosterone-like steroids for several months stopped having normal menstrual cycles. What is the best explanation for this observation?
Correct Answer: D
Rationale: The correct answer is D because testosterone inhibits the hypothalamic secretion of gonadotropin-releasing hormone (GnRH) and the pituitary secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This disruption in the normal hormonal feedback loop leads to the suppression of ovulation and the menstrual cycle. Option A is incorrect because inhibin is not directly affected by testosterone. Option B is incorrect as testosterone does not bind to endometrial receptors directly. Option C is incorrect because testosterone does not stimulate the secretion of FSH and LH from the anterior pituitary.
Question 3 of 5
A 20-year-old woman is not having menstrual cycles. Her plasma progesterone concentration is found to be minimal. What is the explanation for the low level of progesterone?
Correct Answer: D
Rationale: The correct answer is D: No corpus luteum is present. The corpus luteum is responsible for producing progesterone after ovulation. Without a corpus luteum, progesterone levels will be minimal, leading to a lack of menstrual cycles. A: If LH secretion rate is elevated, it would lead to increased corpus luteum formation and progesterone production. B: If LH secretion rate is suppressed, there would be insufficient stimulation for corpus luteum formation and progesterone production. C: FSH is responsible for follicle development, not progesterone production.
Question 4 of 5
Birth control pills containing combinations of synthetic estrogen and progesterone compounds given for the first 21 days of the menstrual cycle are effective in preventing pregnancy. What is the explanation for their efficacy?
Correct Answer: A
Rationale: The correct answer is A. Birth control pills containing estrogen and progesterone prevent the preovulatory surge of luteinizing hormone (LH) secretion from the pituitary gland. This leads to the inhibition of ovulation, preventing the release of an egg from the ovary. Without ovulation, fertilization cannot occur, effectively preventing pregnancy. Choice B is incorrect because birth control pills do not prevent the development of ovarian follicles; they prevent ovulation. Choice C is incorrect because suppressing the function of the corpus luteum is not the primary mechanism of action of birth control pills. Choice D is incorrect because birth control pills do not prevent the normal development of the endometrium; they primarily prevent ovulation.
Question 5 of 5
Sperm are formed in tightly coiled tubes called seminiferous tubules that are found within each ________.
Correct Answer: B
Rationale: The correct answer is B: testis. The seminiferous tubules are located within the testes, where sperm are produced through the process of spermatogenesis. The spermatic cord (A) contains blood vessels, nerves, and the vas deferens but not the seminiferous tubules. The ductus deferens (C) is a tube that carries sperm from the epididymis to the urethra, not where sperm are formed. The epididymis (D) is where sperm mature and are stored but not where they are initially formed. Therefore, the testis is the only choice where the seminiferous tubules are located for sperm production.
