Reproductive System Exam Quizlet

1. What is the role of relaxin hormone?

Correct answer: A

Rationale: The correct answer is A: Relaxation of the symphysis pubis. Relaxin hormone is responsible for loosening the ligaments in the pelvic area, particularly the symphysis pubis, to prepare for childbirth. Choice B, stimulation of milk production, is incorrect as this is primarily regulated by prolactin. Choice C, stimulating the development of the nipple and duct system in the breast, is incorrect as this is mainly influenced by estrogen and progesterone during pregnancy. Therefore, the correct role of relaxin hormone is the relaxation of the symphysis pubis.

2. What causes the changes in appearance seen in boys at the time of puberty?

Correct answer: D

Rationale: During puberty, boys experience physical changes such as growth of facial and body hair, deepening of the voice, and muscle development. These changes are primarily driven by the hormone testosterone. Testosterone is responsible for the development of male secondary sexual characteristics. Therefore, the correct answer is testosterone. Choices A, B, and C are incorrect because prolactin, adrenaline, and estrogen do not play a significant role in the development of male secondary sexual characteristics during puberty.

3. Which of the following structures is responsible for the production of sperm?

Correct answer: C

Rationale: The testes are the male reproductive organs responsible for the production of sperm through a process called spermatogenesis. The epididymis is a structure where sperm mature and are stored temporarily. Seminal vesicles produce a significant portion of the fluid that ultimately becomes semen, but they do not produce sperm. The prostate gland contributes additional fluid to semen but does not produce sperm. Therefore, the correct answer is the testes.

4. When does missed abortion occur?

Correct answer: C

Rationale: Missed abortion occurs when the cervix is closed, and the products of conception remain in the uterus. Choice A describes a missed abortion, not choice C. Choice B describes a complete abortion. Choice D describes a threatened abortion, where the cervix remains closed but there is heavy bleeding.

5. Which of the following is NOT a strategy for family planning?

Correct answer: D

Rationale: The correct answer is D. Expanded programs of immunization are not considered a strategy for family planning. Immunization programs focus on preventing diseases through vaccines and are distinct from family planning strategies, which aim to help individuals and couples plan their desired family size and spacing of children. Choices A, B, and C are all valid strategies for family planning. Integrating family planning services with other reproductive health programs, expanding access to family planning through non-public delivery systems, and targeting family planning services to priority groups are common approaches to improve the availability and effectiveness of family planning services.
