Human Reproductive System Quizlet Questions
Question 1 of 5
Which of the following is NOT a part of
Correct Answer: B
Rationale: The correct answer is B: menarche. Menarche refers to the onset of a female's first menstrual period, not related to male reproductive anatomy. Choice A, labor a male's testis, involves the process of childbirth and is not related to male reproductive anatomy. Choice C, seminiferous tubule, is a part of the male reproductive system where sperm is produced. Choice D, menstruation, is the monthly shedding of the uterine lining in females, not related to male reproductive anatomy. Therefore, menarche is the only choice that does not pertain to male reproductive anatomy.
Question 2 of 5
Ovulation occurs as a result of a surge of what hormone
Correct Answer: C
Rationale: The correct answer is C: luteinising hormone (LH). Ovulation is triggered by a surge of LH from the anterior pituitary gland, which causes the mature follicle to rupture and release the egg. Inhibin (A) inhibits FSH secretion, FSH (B) stimulates follicle development, and progesterone (D) is produced after ovulation to support the uterine lining. Therefore, the surge of LH is the key hormone that directly triggers ovulation.
Question 3 of 5
Which of the following sets of tissues are all part of a developing follicle.
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.
Question 4 of 5
Which of the following is not involved in parturition.
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.
Question 5 of 5
An egg that has been fertilized by a sperm is called a _______________.
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.
