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. Discuss the anatomical/physiological changes in pregnancy under the following: Kidney/renal system
- A. Kidneys increase in size, pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases.
- B. Kidneys decrease in size, and glomerular filtration rate decreases.
- C. There is no change in kidney size or ureter function, but the glomerular filtration rate decreases.
- D. Kidneys shrink, and ureters remain the same.
Correct answer: A
Rationale: During pregnancy, the kidneys increase in size, the pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases. This is due to the increased metabolic demands and hormonal changes during pregnancy. Choice B is incorrect as the kidneys do not decrease in size, and the glomerular filtration rate actually increases. Choice C is incorrect as there are changes in kidney size and ureter function during pregnancy. Choice D is incorrect as the kidneys do not shrink during pregnancy.
3. What is the role of relaxin hormone?
- A. Relaxation of the symphysis pubis.
- B. Stimulation of milk production.
- C. Stimulating the development of the nipple and duct system in the breast.
- D. None of the above.
Correct answer: A
Rationale: The correct answer is A: Relaxation of the symphysis pubis. Relaxin hormone is responsible for loosening the ligaments in the pelvic area, particularly the symphysis pubis, to prepare for childbirth. Choice B, stimulation of milk production, is incorrect as this is primarily regulated by prolactin. Choice C, stimulating the development of the nipple and duct system in the breast, is incorrect as this is mainly influenced by estrogen and progesterone during pregnancy. Therefore, the correct role of relaxin hormone is the relaxation of the symphysis pubis.
4. 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.
5. What type of epithelium lines the vagina?
- A. Ciliated epithelium.
- B. Squamous epithelium.
- C. Columnar epithelium.
- D. Transitional epithelium.
Correct answer: B
Rationale: The correct answer is B: Squamous epithelium. The vagina is lined with non-keratinized stratified squamous epithelium. This type of epithelium provides protection against abrasion and pathogens. Choice A, Ciliated epithelium, is incorrect as ciliated epithelium is found in areas like the fallopian tubes to help move the egg towards the uterus. Choice C, Columnar epithelium, is incorrect as columnar epithelium is typically found in areas like the intestines. Choice D, Transitional epithelium, is incorrect as this type of epithelium is found in areas like the urinary bladder.
