Reproductive System Exam Questions
1. What is the measurement of the breast areola?
- A. 3.5cm
- B. 2.5cm
- C. 4.5cm
- D. 1.5cm
Correct answer: B
Rationale: The correct answer is 2.5 cm. The average measurement of the areola is approximately 2.5 cm. Choices A, C, and D are incorrect as they do not align with the typical measurement of the breast areola.
2. How many arteries are there in an umbilical cord?
- A. Three
- B. One
- C. Two
- D. Four
Correct answer: C
Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.
3. Which structure maintains the uterus in an anteverted and anteflexed position?
- A. Round ligaments
- B. Broad ligaments
- C. Cardinal ligaments
- D. Pubocervical ligaments
Correct answer: A
Rationale: The correct answer is the Round ligaments. The round ligaments are responsible for maintaining the uterus in an anteverted and anteflexed position. These ligaments attach from the sides of the uterus and extend through the inguinal canal to the labia majora. The other choices, Broad ligaments, Cardinal ligaments, and Pubocervical ligaments, have different functions and attachments within the pelvis. Broad ligaments are a double layer of peritoneum that encloses the uterus and supports the uterine tubes. Cardinal ligaments provide support to the cervix and upper vagina. Pubocervical ligaments support the cervix and bladder.
4. What action does the copper used in Copper T have?
- A. Blastocidal
- B. Bacteriostatic
- C. Bacteriocidal
- D. Spermicidal
Correct answer: D
Rationale: The correct answer is D, Spermicidal. The copper in Copper T exerts its action by affecting sperm viability and motility, thus preventing fertilization. Choices A, B, and C are incorrect because Copper T primarily works by preventing sperm from reaching and fertilizing the egg, rather than acting on blastocysts, bacteria, or bacteriocins.
5. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:
- A. Zygote
- B. Blastomere
- C. Morula
- D. Blastocyst
Correct answer: C
Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'
