The clusters of specific glands that cycle are known as ________. produce milk when a woman is
- A. the menstrual phase lactating are called _______.
- B. the secretory phase
- C. lactiferous ducts
- D. menses
Correct Answer: B
Rationale: The correct answer is B: the secretory phase. During the secretory phase of the menstrual cycle, the glands in the breast tissue prepare for potential milk production. This phase occurs after ovulation when the body is getting ready for a possible pregnancy. The other choices are incorrect because:
A: the menstrual phase refers to the shedding of the uterine lining, not the breast glands.
C: lactiferous ducts are the tubes that carry milk from the glands to the nipple, not the clusters of glands themselves.
D: menses refers to the menstrual bleeding period, not the phase in which the breast glands are active for milk production.

Which structure helps regulate the temperature of the testes?
- A. Dartos muscle
- B. Tunica vaginalis
- C. Tunica albuginea
- D. Seminiferous tubules
Correct Answer: A
Rationale: The correct answer is A: Dartos muscle. The Dartos muscle is a layer of smooth muscle in the scrotum that contracts and relaxes to regulate the temperature of the testes by adjusting their distance from the body for temperature control. The other choices are incorrect because:
B: Tunica vaginalis is a serous membrane that surrounds the testes, providing support and lubrication.
C: Tunica albuginea is a dense fibrous membrane that covers the testes, providing structural support.
D: Seminiferous tubules are the site of sperm production in the testes, but do not play a direct role in temperature regulation.
What is line “D” pointing to?
- A. Follicular fluid
- B. Germinal epithelium
- C. Ovarian cortex
- D. Ovarian medulla
Correct Answer: D
Rationale: The correct answer is D: Ovarian medulla. Line "D" is pointing to the inner region of the ovary known as the medulla, which contains blood vessels, nerves, and connective tissue. This is confirmed by the location and characteristics of the structures in that region.
Explanation:
1. Follicular fluid (Choice A) is found within the follicles in the ovarian cortex, not in the medulla.
2. Germinal epithelium (Choice B) is the outermost layer of the ovary, whereas the medulla is located deeper within the ovary.
3. Ovarian cortex (Choice C) is the outer layer of the ovary where follicles develop, while the medulla is the inner region.
In summary, the correct answer is D (Ovarian medulla) as it accurately identifies the inner region of the ovary where blood vessels and connective tissue are located, distinguishing it from the other choices.
The menstrual cycle is triggered each month by
- A. the release of blood from the uterus
- B. the buildup of the lining of the uterus
- C. hormones
- D. sexual intercourse
Correct Answer: C
Rationale: The correct answer is C: hormones. Hormones, specifically estrogen and progesterone, control the menstrual cycle by regulating the release of an egg from the ovary, thickening the uterine lining, and preparing the body for pregnancy or menstruation. Hormonal fluctuations throughout the cycle signal the body to shed the uterine lining if fertilization does not occur. Choices A and B are incorrect as they describe events during the menstrual cycle rather than the trigger itself. Choice D, sexual intercourse, does not directly trigger the menstrual cycle but may lead to conception, which is one of the outcomes of the menstrual cycle.
Select the following structures which participate in forming the pelvic brim
- A. Arcuate line
- B. Margin ala of sacrum
- C. Pubic tubercle
- D. Sacral promontory
Correct Answer: A
Rationale: The correct answer is A: Arcuate line. The pelvic brim is formed by structures at the pelvic inlet. The arcuate line is a ridge on the inner surface of the ilium that contributes to the boundary of the pelvic brim. The other choices, B: Marginal ala of sacrum, C: Pubic tubercle, and D: Sacral promontory, do not directly participate in forming the pelvic brim. The marginal ala of the sacrum is part of the sacrum, the pubic tubercle is located on the pubis bone, and the sacral promontory is a landmark on the sacrum but does not contribute to the pelvic brim.

- B. A dimpling of the skin over the lesion
