Reproductive System Exam Quizlet
1. 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.
2. What is the inner lining of the non-pregnant uterus called?
- A. Decidua
- B. Myometrium
- C. Endometrium
- D. Sponge layer
Correct answer: C
Rationale: The correct answer is C, Endometrium. The endometrium is the inner lining of the non-pregnant uterus that undergoes cyclic changes in response to hormonal fluctuations during the menstrual cycle. Choice A, Decidua, is the specialized membrane formed during pregnancy. Choice B, Myometrium, refers to the middle layer of the uterine wall composed of smooth muscle. Choice D, Sponge layer, is not a term used to describe the inner lining of the uterus.
3. What is an organelle that helps the sperm to penetrate the ovum?
- A. Acrosome
- B. Zona pellucida
- C. Megalis
- D. None of the above
Correct answer: A
Rationale: The correct answer is Acrosome. The acrosome is an organelle located at the head of a sperm cell and contains enzymes that aid in the penetration of the ovum during fertilization. The Zona pellucida is a glycoprotein membrane surrounding the ovum, not an organelle. Megalis is not a relevant organelle in this context. Therefore, the correct choice is A, Acrosome.
4. What is required for privacy in reproductive health services?
- A. Covering windows and placing partitions between examination areas.
- B. Placing examination tables so that women will be exposed during exams.
- C. Allowing healthcare staff to discuss patients openly in the clinic.
- D. Forcing patients to undergo procedures without proper explanation.
Correct answer: A
Rationale: Privacy in reproductive health services necessitates maintaining confidentiality and creating a private environment for patients. This includes covering windows and using partitions between examination areas to protect the patient's privacy. Choice B is incorrect as it suggests exposing women during exams, which violates privacy. Choice C is incorrect because discussing patients openly breaches confidentiality. Choice D is incorrect as it goes against informed consent and proper communication, which are essential components of respecting patient autonomy and privacy.
5. Which of the following is a symptom of menopause?
- A. Bleeding per vagina
- B. Sleeping all the time
- C. Insomnia
- D. Increased concentration
Correct answer: C
Rationale: Insomnia is a common symptom of menopause. During menopause, hormonal changes can lead to sleep disturbances, including difficulty falling asleep or staying asleep. Choice A, 'Bleeding per vagina,' is not a typical symptom of menopause but should prompt further evaluation. Choice B, 'Sleeping all the time,' is not a common symptom of menopause; in fact, insomnia, rather than excessive sleep, is more prevalent. Choice D, 'Increased concentration,' is not a symptom of menopause; cognitive changes like forgetfulness or difficulty concentrating may occur, but increased concentration is not a typical manifestation.
