Reproductive System Exam Quizlet

1. How does human sperm move?

Correct answer: A

Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.

2. What is the area of the uterus where the fallopian tubes are inserted known as?

Correct answer: D

Rationale: The correct answer is D, Cornua. The cornua refers to the upper, horn-like parts of the uterus where the fallopian tubes are inserted. The fundus (choice A) is the rounded top portion of the uterus, the corpus or body (choice B) is the main part of the uterus excluding the cervix and fundus, and the cavity (choice C) refers to the internal space within the uterus. Therefore, choices A, B, and C are incorrect as they do not specifically denote the area where the fallopian tubes are inserted.

3. A woman is considered to be in menopause if she has experienced the cessation of her menses for a period of:

Correct answer: B

Rationale: Menopause is defined as the cessation of menses for 12 months. This period is significant because it indicates the end of a woman's reproductive years. Choices A, C, and D are incorrect as they do not align with the established criteria for defining menopause.

4. Expanded access to family planning is facilitated by the use of:

Correct answer: D

Rationale: Expanded access to family planning is achieved through various means, including utilizing the private sector, employing social marketing strategies, implementing community-based programs, and emphasizing Information, Education, and Communication initiatives. Each of the options plays a crucial role in enhancing access to family planning services. Therefore, the correct answer is 'All of the above.' Option A focuses on involving the private sector and social marketing, which are essential components. Option B emphasizes community-based programs, which are another key aspect. Option C highlights the significance of Information, Education, and Communication in promoting family planning. As all these strategies are integral to expanding access to family planning, the most comprehensive answer is 'All of the above.'

5. Which contraceptive option suppresses sperm motility and inhibits the implantation of the blastocyst?

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.
