The Human Reproductive System Questions
Question 1 of 5
Ovulation occurs in response to the release of an anterior pituitary hormone known as ________ hormone
Correct Answer: C
Rationale: The correct answer is C: luteinizing hormone (LH). LH is released by the anterior pituitary gland to trigger ovulation in females. It causes the mature ovarian follicle to release an egg during the menstrual cycle. Antidiuretic hormone (A) is involved in regulating water balance, not ovulation. Thyroid-stimulating hormone (B) stimulates the thyroid gland, not the ovaries. Follicle-stimulating hormone (D) helps in the development of ovarian follicles, but it is not responsible for triggering ovulation. Therefore, C is the correct answer as it directly stimulates the release of the egg during ovulation.
Question 2 of 5
Which of the following is a false description of the negative feedback loop involved in the production of testosterone?
Correct Answer: A
Rationale: The correct answer is A because follicle stimulating hormone (FSH) is not directly involved in the negative feedback loop for testosterone production. The negative feedback loop for testosterone involves the hypothalamus releasing GnRH, which stimulates the pituitary gland to release luteinizing hormone (LH), which then stimulates the Leydig cells in the testes to produce testosterone. Rising levels of testosterone inhibit the release of GnRH and LH through negative feedback to maintain hormonal balance. Choices B, C, and D are incorrect because they accurately describe components of the negative feedback loop for testosterone production.
Question 3 of 5
How long are the typical ovarian and uterine (menstrual) cycles in a female?
Correct Answer: C
Rationale: The correct answer is C (28 days) because the typical ovarian and uterine (menstrual) cycles in a female are both around this duration. The menstrual cycle is typically 28 days, with ovulation occurring around day 14. This cycle is regulated by hormonal fluctuations and prepares the uterus for potential pregnancy. Choices A, B, and D are incorrect because a 7-day cycle is too short for a full menstrual cycle, a 14-day cycle is typically the duration of ovulation, and a 40-day cycle is longer than the average menstrual cycle length.
Question 4 of 5
The gonads produce sex cells, also spermatids into sperm is known as known as ________, ________.
Correct Answer: D
Rationale: The correct answer is D: spermiogenesis. Spermiogenesis is the process where spermatids mature into sperm cells in the testes. The gonads (testes in males) produce sex cells, but zygotes are formed through fertilization, not spermiogenesis. Mitosis is a type of cell division for growth and repair, not sperm production. Interstitial cells are found in the testes but are responsible for producing testosterone, not the maturation of spermatids into sperm cells. Therefore, option D is the correct choice as it specifically relates to the transformation of spermatids into sperm cells in the testes.
Question 5 of 5
The distal portion of the male urethra ________. that runs the length of the penis is the epididymis, ductus (vas) ________.
Correct Answer: D
Rationale: The correct answer is D because the question is referring to the male urethra, not the epididymis or vas deferens. The distal portion of the male urethra that runs the length of the penis is the membranous urethra and the spongy (penile) urethra. A and B are incorrect as they mention the prostatic urethra, which is not the distal portion that runs the length of the penis. Choice C is incorrect as it only mentions the membranous urethra and does not address the full distal portion.
