Reproductive System Exam Quizlet

1. How does human sperm move?

A. Flagella
B. Cilia
C. Neutrophils
D. None of the above

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. Which one of the following statements is NOT true about menstruation?

A. The average amount of menstrual flow is 50 to 90 ml.
B. The menstrual flow constitutes serous fluid, necrotic slough.
C. The cycle is influenced by the ovarian hormones Estrogen and progesterone.
D. The menstrual flow has non-clotting blood.

Correct answer: D

Rationale: The correct answer is D. The statement that menstrual flow has non-clotting blood is incorrect because menstrual blood can indeed clot. Choices A, B, and C are all true statements about menstruation. Choice A reflects the average amount of menstrual flow, choice B describes the components of menstrual flow, and choice C correctly identifies the ovarian hormones that influence the menstrual cycle.

3. 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.

4. During the counseling session, you can also use the acronym, CLEAR. The letter E stands for:

A. Encourage and assure the client of effective use of the method
B. Explain how to use the method
C. Tell the client about modern FP methods available, and discuss each in detail
D. Explain all possible complications

Correct answer: B

Rationale: The correct answer is B: 'Explain how to use the method.' In the acronym CLEAR, the letter E specifically refers to explaining how to use the method, emphasizing the importance of providing clear instructions and guidance to the client. Choices A, C, and D are incorrect because they do not accurately represent what the letter E stands for in the given context. Encouraging and assuring the client, discussing modern FP methods in detail, and explaining possible complications are important aspects of counseling but do not align with the specific focus of 'Explain how to use the method,' as indicated by the acronym.

5. Which of the following is subsidiary uterine support?

A. Suspensory ligament
B. Cardinal ligament
C. Transcervical ligament
D. Maklouf ligament

Correct answer: B

Rationale: The correct answer is B: Cardinal ligament. The cardinal ligament is a primary uterine support structure that helps to anchor the uterus in place. The suspensory ligament also provides support for the uterus but is not considered a subsidiary uterine support. The transcervical ligament does not exist in anatomical terminology. The Maklouf ligament is a fictitious term and not recognized as a subsidiary uterine support structure.
