Reproductive System Exam Questions
1. The endometrial tissue of the cervix is arranged in folds known as:
- A. Racemose glands
- B. Rugae
- C. Arbor vitae
- D. Peritoneum
Correct answer: B
Rationale: The endometrial tissue of the cervix is arranged in folds known as rugae, not Arbor vitae. Rugae are commonly found in anatomical structures like the stomach and bladder to allow expansion. Choices A, C, and D are incorrect. Racemose glands refer to branched compound glands, Arbor vitae is the tree-like appearance of the cerebellum, and Peritoneum is the serous membrane lining the abdominal cavity.
2. Amniocentesis, a prenatal diagnostic test used to determine fetal sex, genetic anomalies, and biochemical abnormalities, is based on:
- A. The karyotyping of the amniotic fluid
- B. Chorionic villus sampling
- C. Umbilical cord blood sampling
- D. Ultrasound
Correct answer: A
Rationale: The correct answer is A. Amniocentesis involves the analysis of the fetal cells present in the amniotic fluid, which is extracted from the amniotic sac surrounding the developing fetus. This fluid contains cells shed by the fetus, which can be cultured and analyzed to obtain a karyotype, providing information about the fetal sex, genetic anomalies, and biochemical abnormalities. Choices B, C, and D are incorrect because chorionic villus sampling involves obtaining a sample of the chorionic villi from the placenta, not the amniotic fluid; umbilical cord blood sampling is typically used for other purposes like assessing the baby's blood for infections or genetic disorders; and ultrasound is a diagnostic imaging technique that does not involve the analysis of fetal cells for genetic information.
3. 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.
4. What is dysmenorrhoea?
- A. Heavy menstruation
- B. Light menstruation
- C. Painful menstruation
- D. Infrequent menstruation
Correct answer: C
Rationale: Dysmenorrhoea is the medical term for painful menstruation. It is characterized by cramp-like abdominal pain that occurs just before or during menstruation. Choice A, heavy menstruation, is referred to as menorrhagia. Choice B, light menstruation, is not a term used to describe a specific menstrual condition. Choice D, infrequent menstruation, is known as oligomenorrhea, not dysmenorrhoea.
5. What is amniocentesis used to detect?
- A. Sexually transmitted diseases
- B. Presence of certain genetic disorders
- C. Causes of infertility
- D. Presence of pneumonia germs
Correct answer: B
Rationale: Amniocentesis is a prenatal test used to detect certain genetic disorders in a developing fetus. It involves collecting a small sample of the amniotic fluid surrounding the fetus and analyzing the genetic material present in the cells. This test is not used to detect sexually transmitted diseases, causes of infertility, or the presence of pneumonia germs. Therefore, the correct answer is B.
