Anatomy and Physiology of the Female Reproductive System Questions
Question 1 of 5
Ova and sperm are also known as which of the following?
Correct Answer: B
Rationale: The correct answer is B: Gametes. Ova and sperm are reproductive cells involved in sexual reproduction. Gametes are specialized cells that combine during fertilization to form a new organism. They are distinct from gonads (A), which are the organs that produce gametes. Stem cells (C) are undifferentiated cells that can develop into various cell types, not specific to ova and sperm. Hormones (D) are chemical messengers produced by endocrine glands, not directly related to ova and sperm production.
Question 2 of 5
After Sam fathers five children, he and his wife decide that he should have a vasectomy, which is a cutting and removal of a small section of each vas deferens. Why will this cause Sam to be infertile?
Correct Answer: B
Rationale: Step 1: Vasectomy involves cutting and removing a small section of each vas deferens, the tubes that carry sperm from the testicles to the urethra. Step 2: By severing the vas deferens, sperm are physically blocked from reaching the urethra. Step 3: Without the ability for sperm to travel through the vas deferens to the urethra, they cannot be ejaculated during coitus. Step 4: Therefore, choice B is correct - the sperm will not be able to get from the epididymis to the urethra, causing infertility. Summary: Choice A is incorrect because ejaculation is the release of semen, not sperm. Choice C is incorrect as the testicles continue to produce sperm, but the sperm cannot reach the urethra. Choice D is incorrect as the acidity of seminal fluid does not affect the ability of sperm to travel through the vas deferens.
Question 3 of 5
What does FSH primarily act to stimulate?
Correct Answer: C
Rationale: FSH primarily acts to stimulate the maturation of the ovarian follicle. FSH facilitates the growth and development of the follicle in the ovary, leading to the release of a mature ovum during ovulation. This process is essential for successful reproduction. Choice A is incorrect because the development of the uterine endometrium is primarily influenced by estrogen and progesterone. Choice B is incorrect as the release of the mature ovum is triggered by the surge in luteinizing hormone (LH), not FSH. Choice D is incorrect as the development of the ovary itself is not a direct function of FSH.
Question 4 of 5
The stimulation of initial milk production and release in the breast is accomplished by which hormones? Select all that apply.
Correct Answer:
Rationale: Correct Answer: A (Oxytocin), C (Prolactin) Rationale: 1. Oxytocin stimulates milk ejection (let-down reflex) by contracting the muscles around the alveoli, releasing milk. 2. Prolactin is responsible for the production of milk in the mammary glands. Summary of Other Choices: - Progesterone: Plays a role in preparing the breast for lactation but doesn't directly stimulate milk production. - Luteinizing hormone: Primarily involved in ovulation and corpus luteum formation, not milk production.
Question 5 of 5
What is the primary structural difference between the male and female urethra?
Correct Answer: B
Rationale: The correct answer is B: The male urethra is up to three times as long as the female urethra. This is because the male urethra serves a dual function - for both urine and semen passage, requiring a longer length for transportation. In contrast, the female urethra is shorter and primarily functions for urine passage only. Choices A, C, and D are incorrect as they do not address the primary structural difference in length between the male and female urethra.
