The ovarian phase between the end of menstruation and beginning of ovulation is the
- A. Menstrual phase
- B. Preovulatory phase
- C. Proliferative phase
- D. Follicular phase
Correct Answer: C
Rationale: The correct answer is C: Proliferative phase. During this phase, the endometrium thickens in preparation for a potential implantation of a fertilized egg. This phase occurs after the menstrual phase and before ovulation, marking the time when the ovarian follicles are developing under the influence of FSH. The other choices are incorrect because the menstrual phase (A) refers to the shedding of the endometrium, the preovulatory phase (B) occurs just before ovulation, and the follicular phase (D) includes both the menstrual and preovulatory phases.
Which of the following is a form of sexual reproduction?
- A. Fragmentation.
- B. Parthenogenesis.
- C. Budding.
- D. Hermaphroditism
Correct Answer: D
Rationale: Step 1: Define sexual reproduction as the process involving the fusion of gametes from two parents.
Step 2: Hermaphroditism refers to an organism having both male and female reproductive organs for self-fertilization.
Step 3: In hermaphroditism, there is still a fusion of gametes, fulfilling the criteria of sexual reproduction.
Step 4: Fragmentation, parthenogenesis, and budding are forms of asexual reproduction, not involving the fusion of gametes.
Step 5: Therefore, the correct answer is D (Hermaphroditism) as it aligns with the definition and process of sexual reproduction.
There are ____________ facial bones
- A. 14
- B. 22
- C. 50
- D. 16
Correct Answer: B
Rationale: The correct answer is B: 22. There are a total of 22 facial bones in the human skull. These bones include the mandible, maxilla, zygomatic bone, nasal bone, and others. Understanding human anatomy is crucial for healthcare professionals. Choice A (14) is too low and does not accurately represent the number of facial bones. Choice C (50) is too high and exceeds the actual count of facial bones. Choice D (16) is also incorrect as it falls short of the correct count of 22. Knowing the exact number of facial bones is important for various medical fields such as surgery, dentistry, and radiology.
Which structure will actually become the fetus?
- A. morula
- B. blastocyst
- C. inner cell mass
- D. zygote
Correct Answer: C
Rationale: The correct answer is C: inner cell mass. After fertilization, the zygote undergoes several cell divisions to form a hollow ball of cells called a blastocyst. Within the blastocyst, the inner cell mass contains cells that will develop into the fetus. The morula is an earlier stage consisting of a solid ball of cells. The zygote is the initial cell formed from the fusion of egg and sperm, but it does not directly become the fetus. Therefore, the inner cell mass is the structure that will actually develop into the fetus, making it the correct answer.
Parturition is another term for
- A. secretory phase ________.
- B. placental stage
- C. menopause
- D. postpartum stage
Correct Answer: D
Rationale: Parturition refers to the process of giving birth. The postpartum stage immediately follows childbirth, involving recovery and adjustment to motherhood. The secretory phase is a phase of the menstrual cycle involving hormonal changes, not related to childbirth. The placental stage refers to the stage after the baby is born when the placenta is delivered. Menopause is the natural cessation of menstruation and fertility in women, occurring later in life and not related to childbirth. Therefore, the correct answer is D because it directly relates to the process of giving birth.
