The Reproductive System Quizlet Questions
Question 1 of 5
A “birth control” compound for men has been sought for several decades. Which of the following would provide effective sterility?
Correct Answer: C
Rationale: The correct answer is C: Substance that blocks the actions of follicle-stimulating hormone. By blocking the actions of FSH, sperm production in the testes would be inhibited, leading to effective sterility. FSH plays a crucial role in stimulating sperm production, so blocking its actions would prevent the development of mature sperm. Explanation for why the other choices are incorrect: A: Substance that mimics the actions of luteinizing hormone - Mimicking LH would not necessarily lead to effective sterility in men. B: Substance that blocks the actions of inhibin - Inhibin regulates FSH secretion but blocking it would not directly lead to effective sterility. D: Substance that mimics the actions of gonadotropin-releasing hormone - Mimicking GnRH would not directly impact sperm production and sterility.
Question 2 of 5
Which hormone is produced by the corpus luteum that helps maintain pregnancy?
Correct Answer: C
Rationale: The correct answer is C: Progesterone. The corpus luteum produces progesterone, which is essential for maintaining the uterine lining and supporting early pregnancy. Progesterone helps prevent contractions of the uterus and supports the development of the placenta. Estrogen (A) is important for the initial thickening of the uterine lining but does not play a direct role in maintaining pregnancy. Testosterone (B) is not involved in pregnancy maintenance. Relaxin (D) helps relax the uterine muscles but is not primarily responsible for maintaining pregnancy.
Question 3 of 5
Which one of the following is not one of the secondary sex characteristics typical of males?
Correct Answer: D
Rationale: The correct answer is D: Development of breast tissue. This is not a secondary sex characteristic typical of males because breast development is a primary sex characteristic associated with females due to the presence of estrogen. In males, the secondary sex characteristics include deepening voice, increased growth of body hair, and enlargement of skeletal muscle mass due to the effects of testosterone. Breast tissue development in males, known as gynecomastia, is abnormal and can be caused by hormonal imbalances or certain medical conditions.
Question 4 of 5
Which hormone is necessary for the growth of endometrial glands, which are important for the sustenance of a growing embryo until its implantation?
Correct Answer: C
Rationale: The correct answer is C: Progesterone. Progesterone is necessary for the growth of endometrial glands as it prepares the endometrium for implantation of the embryo. LH is responsible for ovulation, not endometrial gland growth. Testosterone is a male sex hormone and not directly involved in endometrial gland growth. Inhibin regulates FSH secretion, not endometrial gland growth.
Question 5 of 5
A mature ovarian follicle that is ready upper portion of the urethra just below to be ejected from an ovary is called a the junction with the urinary bladder. ________.
Correct Answer: D
Rationale: The correct answer is D: vesicular (Graafian) follicle. This structure is the final stage of maturation of an ovarian follicle before ovulation. It is characterized by a fluid-filled cavity and a bulging appearance on the surface of the ovary. It releases the mature egg during ovulation. Rationale: 1. Ejaculatory (choice A) relates to the male reproductive system, not the female reproductive system. 2. Primary oocyte (choice B) refers to an immature egg cell, not a mature follicle. 3. Seminal (choice C) is related to semen production in males, not the female ovary. In summary, the vesicular (Graafian) follicle (choice D) is the correct answer as it accurately describes the final stage of maturation of an ovarian follicle before ovulation.
