The clusters of specific glands that cycle are known as ________. produce milk when a woman is

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.

Correct Answer: D

Rationale: The correct answer is D because all the tissues mentioned (zona pellucida, cumulus oophorous, theca) are indeed part of a developing follicle. The zona pellucida is the glycoprotein layer surrounding the oocyte, the cumulus oophorous is a cluster of granulosa cells surrounding the oocyte, and the theca is a layer of connective tissue surrounding the follicle. Choice A is incorrect because the corpus luteum is not part of a developing follicle. Choice B is incorrect because the acrosome is a structure in sperm, not the follicle. Choice C is incorrect because the corpus luteum is not part of a developing follicle, and the oocyte is already present within the follicle but is not considered a part of it.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Parturition is the process of giving birth. 2. Luteinising hormone (LH) is primarily involved in the menstrual cycle and ovulation, not parturition. 3. Prostaglandins and oxytocin play crucial roles in initiating and sustaining labor. 4. An increase in uterine oxytocin receptors is necessary for effective uterine contractions during parturition. 5. Therefore, an increase in luteinising hormone secretion is not involved in parturition. Summary of incorrect choices: A: Incorrect - an increase in prostaglandin secretion is involved in parturition. B: Incorrect - an increase in uterine oxytocin receptors is necessary for parturition. D: Incorrect - an increase in oxytocin secretion is crucial for initiating labor.

Correct Answer: B

Rationale: The correct answer is B: zygote. After fertilization, when the sperm and egg unite, they form a zygote. This is the initial stage of a new organism's development. Implantation (A) occurs when the embryo attaches to the uterus. Embryo (C) is the term for the developing organism after the zygote stage. Breast (D) is not related to the fertilization process. In this context, zygote is the most appropriate term as it specifically refers to the newly formed cell after fertilization.

Correct Answer: B

Rationale: The correct answer is B: perineorrhaphy. "Perineorrhaphy" refers to the surgical suturing of the perineum. The term is derived from "perineum" (the area between the anus and the genitalia) and "rrhaphy" (meaning suture). A: cervicography - This term refers to a diagnostic procedure involving imaging of the cervix, not related to suturing the perineum. C: cervicorrhapy - This term does not exist in medical terminology and is not related to suturing the perineum. D: cervicorrhexis - This term refers to the tearing of the cervix, not the suturing of the perineum. In summary, perineorrhaphy is the correct term as it specifically refers to suturing the perineum, while the other choices are unrelated to this procedure.
