Human Reproductive System Questions
Question 1 of 5
Which is a sign of benign prostatic hyperplasia?
Correct Answer: D
Rationale: The correct answer is D: Nocturia. Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland, leading to urinary symptoms like frequent urination, especially at night (nocturia). Weight loss, bone pain, and fever are not typical signs of BPH. Nocturia is a common symptom due to the prostate gland pressing against the urethra, causing urinary retention. It is important to differentiate BPH symptoms from other potential causes to provide appropriate treatment.
Question 2 of 5
As menstruation ends estrogen levels in the blood rise rapidly. What is the source of the estrogen?
Correct Answer: B
Rationale: The correct answer is B: Developing follicles. After menstruation, the developing follicles in the ovaries produce estrogen. This estrogen is responsible for thickening the endometrium in preparation for potential implantation of a fertilized egg. The corpus luteum produces progesterone, not estrogen. The endometrium is the inner lining of the uterus and is not a direct source of estrogen. Stromal cells of the ovaries are supportive cells and do not produce estrogen.
Question 3 of 5
During pregnancy, the uterine smooth muscle is quiescent. During the 9th month of gestation the uterine muscle becomes progressively more excitable. What factors contribute to the increase in excitability?
Correct Answer: B
Rationale: The correct answer is B: Progesterone synthesis by the placenta decreases. Progesterone maintains uterine quiescence during pregnancy by inhibiting uterine contractions. As progesterone levels decline towards the end of pregnancy, the uterine muscle becomes more excitable. Placental estrogen synthesis (Choice A) does not directly affect uterine excitability. Uterine blood flow (Choice C) is not a direct factor in uterine muscle excitability. Prostaglandin E2 (Choice D) actually increases towards the end of pregnancy, contributing to uterine contractions rather than decreasing excitability.
Question 4 of 5
Levels of transcortin are elevated in a pregnant woman. Which of the following laboratory findings would be expected in this patient?
Correct Answer: A
Rationale: Rationale: Elevated levels of transcortin in a pregnant woman lead to an increase in total plasma cortisol concentration. Transcortin binds to cortisol, increasing its total concentration but reducing the amount of free (non-protein-bound) cortisol. Choice A is correct as total cortisol concentration increases due to transcortin binding. Choices B and D are incorrect as free cortisol concentration decreases. Choice C is incorrect as total cortisol concentration is elevated, not decreased.
Question 5 of 5
The gonads, or primary sex organs, produce sex cells, also known as ________.
Correct Answer: C
Rationale: The correct answer is C: gametes. Gonads produce sex cells, which are haploid cells involved in reproduction. Gametes are the mature, haploid male or female germ cells (sperm or egg) produced by the gonads. Zygotes are formed when gametes fuse during fertilization, not produced by gonads. Interstitial cells are found in the testes and produce hormones, not sex cells. Spermatids are immature male germ cells that develop into sperm, not the primary sex cells produced by gonads.
