Reproductive System Exam Quizlet
1. Which one of the following is not a stage in the ovarian cycle of the menstrual cycle?
- A. Recruitment of Graafian follicle
- B. Selection of dominant follicle
- C. Luteal phase
- D. Formation of corpus luteum
Correct answer: A
Rationale: The correct answer is A. The recruitment of the Graafian follicle is indeed a stage in the ovarian cycle. During the ovarian cycle, the primary follicles are recruited to develop further, leading to the formation of the Graafian follicle. The selection of the dominant follicle, luteal phase, and formation of the corpus luteum are other essential stages in the ovarian cycle. Therefore, option A is not correct as it is a crucial phase in the process of ovulation and fertilization.
2. Which statement accurately describes the female pelvis?
- A. Gynaecoid pelvis has a wedge-shaped inlet
- B. Platypelloid pelvis has an oval inlet
- C. Anthropoid pelvis has a long narrow oval inlet
- D. Android pelvis is wedge-shaped
Correct answer: B
Rationale: The correct answer is B because the Platypelloid pelvis indeed has an oval inlet. Gynaecoid pelvis, not mentioned in the choices, has a round inlet. Anthropoid pelvis has a long, narrow oval inlet, which makes choice C incorrect. Choice D is incorrect as the Android pelvis is actually heart-shaped with a narrowed inlet.
3. Which animal is an ovoviviparous animal?
- A. Basking shark
- B. Bonobo
- C. Blue shark
- D. None of the above
Correct answer: C
Rationale: The correct answer is the Blue shark. Ovoviviparous animals produce eggs that develop inside the body of the parent, and the offspring are born alive. The basking shark does not fall under this category as it is ovoviviparous, meaning it lays eggs that hatch inside the female's body. The bonobo is a separate species and not relevant to the question.
4. The following are delays associated with maternal mortality EXCEPT:
- A. Delay in recognizing danger signs
- B. Delay in arrival at a health facility
- C. Delay in initiating treatment
- D. Excessive blood loss
Correct answer: D
Rationale: The correct answer is D. Excessive blood loss is not a delay associated with maternal mortality but rather a direct complication. Delays in recognizing danger signs, arriving at a health facility, and initiating treatment are factors that can contribute to maternal mortality by impeding timely access to necessary care.
5. How many autosomes does a human primary spermatocyte have?
- A. 34
- B. 44
- C. 54
- D. 33
Correct answer: B
Rationale: A human primary spermatocyte has 44 autosomes. Autosomes are chromosomes that are not involved in determining an individual's sex. In humans, there are a total of 46 chromosomes in a somatic cell, with 22 pairs of autosomes and one pair of sex chromosomes. Therefore, the correct answer is 44 autosomes, making choice B the correct answer. Choices A, C, and D are incorrect as they do not represent the accurate number of autosomes in a human primary spermatocyte.
