Reproductive System Exam Quizlet

1. Discuss the anatomical/physiological changes in pregnancy related to the breasts.

Correct answer: A

Rationale: During pregnancy, the breasts undergo significant anatomical and physiological changes. These changes include increased breast tenderness, an increase in circulatory supply to the breasts, resulting in breast enlargement, and the secretion of colostrum. Choice B is incorrect as breast tenderness actually increases during pregnancy. Choice C is incorrect as the circulatory supply to the breasts increases rather than reduces. Choice D is incorrect as breasts do undergo notable changes during pregnancy.

2. What is the most common symptom in all clinical types of abortion EXCEPT:

Correct answer: C

Rationale: The correct answer is C. 'Show' is not a common symptom in all types of abortion. Lower abdominal pain, per vaginal bleeding, and backache are common symptoms associated with abortion. Lower abdominal pain may result from uterine contractions, per vaginal bleeding is a typical presentation, and backache can be a symptom due to the process of abortion. 'Show' refers to the mucus plug that blocks the cervix during pregnancy and is not a typical symptom of abortion.

3. What is the primary use of Bromocriptine?

Correct answer: C

Rationale: Bromocriptine is primarily used to affect milk production. It is a medication commonly prescribed to help suppress lactation, particularly in cases of postpartum breast engorgement or when stopping breastfeeding. Choices A, B, and D are incorrect as Bromocriptine is not indicated for relieving constriction ring, managing post-partum hemorrhage, or treating pre-eclampsia.

4. _______ is a lytic enzyme released by the sperm.

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

5. Where does the ovum receive the sperm?

Correct answer: C

Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.
