Reproductive System Exam Quizlet
1. What forms the vaginal lining?
- A. Squamous epithelium
- B. Stratified epithelium
- C. Vascular connective tissue
- D. Muscle coat
Correct answer: A
Rationale: The vaginal lining is primarily formed by squamous epithelium. Squamous epithelium is the correct answer because it is the type of epithelium that lines the vaginal canal. Stratified epithelium consists of multiple layers and is not the primary type found in the vaginal lining. Vascular connective tissue and muscle coat are not the main components of the vaginal lining, making them incorrect choices.
2. Where does fertilization normally occur?
- A. Ampulla
- B. Interstitial portion
- C. Isthmus
- D. Infundibulum
Correct answer: A
Rationale: Fertilization typically occurs in the ampulla of the fallopian tube. The ampulla provides the ideal environment for fertilization due to the presence of cilia that help transport the egg and sperm, as well as the nourishing fluid within this region. The interstitial portion, isthmus, and infundibulum of the fallopian tube are not the primary sites for fertilization. The interstitial portion connects the fallopian tube to the uterine cavity, the isthmus is the narrowest part near the uterus, and the infundibulum is the funnel-shaped end near the ovary, where the egg is captured after ovulation.
3. At 3-4 weeks of pregnancy, the breast changes include:
- A. Darkening of the nipple.
- B. Prickling, tingling sensation.
- C. Breast becomes tender.
- D. Colostrum can be expressed.
Correct answer: C
Rationale: At 3-4 weeks of pregnancy, breast changes commonly involve tenderness due to hormonal fluctuations. Darkening of the nipple (Choice A) typically occurs later in pregnancy. Prickling, tingling sensations (Choice B) are more associated with early pregnancy due to increased blood flow to the breast area. Colostrum production (Choice D) usually begins later in pregnancy, closer to the end of the third trimester.
4. Which contraceptive option suppresses sperm motility and inhibits the implantation of the blastocyst?
- A. Copper-T
- B. Diaphragm
- C. Contraceptive pills
- D. Condom
Correct answer: A
Rationale: The correct answer is A, Copper-T. Copper-T is an intrauterine device that releases copper ions, which suppress sperm motility and inhibit the implantation of the blastocyst. This method mainly works by preventing fertilization and, if fertilization occurs, by making the endometrium less receptive to implantation. Choices B, C, and D are incorrect. The diaphragm is a barrier method that prevents sperm from reaching the cervix; contraceptive pills mainly work by suppressing ovulation and altering cervical mucus to prevent sperm from reaching the egg; condoms are barrier methods that prevent sperm from entering the vagina.
5. What type of epithelium lines the fallopian tubes?
- A. Ciliated epithelium.
- B. Stratified epithelium.
- C. Columnar epithelium.
- D. Endometrium.
Correct answer: A
Rationale: The correct answer is A: Ciliated epithelium. The fallopian tubes are lined with ciliated epithelium, which helps to move the egg from the ovary to the uterus. Choice B, Stratified epithelium, is incorrect because the fallopian tubes are lined with a single layer of cells. Choice C, Columnar epithelium, is incorrect as it does not accurately describe the lining of the fallopian tubes. Choice D, Endometrium, is incorrect because the endometrium is the inner lining of the uterus, not the fallopian tubes.
