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. In missed abortion, what will the woman often experience?
- A. Severe cramping and lower abdominal pains
- B. Brownish vaginal discharge
- C. Profuse per vagina bleeding
- D. Open cervical OS
Correct answer: B
Rationale: In missed abortion, the woman often experiences brownish vaginal discharge. This is known as a symptom of missed abortion. Severe cramping and lower abdominal pains (Choice A) are more characteristic of an incomplete abortion, where not all pregnancy tissue is expelled. Profuse per vagina bleeding (Choice C) is more commonly associated with a complete abortion. Open cervical OS (Choice D) is a physical finding and not a typical symptom reported by the woman in missed abortion.
4. What is an organelle that helps the sperm to penetrate the ovum?
- A. Acrosome
- B. Zona pellucida
- C. Megalis
- D. None of the above
Correct answer: A
Rationale: The correct answer is Acrosome. The acrosome is an organelle located at the head of a sperm cell and contains enzymes that aid in the penetration of the ovum during fertilization. The Zona pellucida is a glycoprotein membrane surrounding the ovum, not an organelle. Megalis is not a relevant organelle in this context. Therefore, the correct choice is A, Acrosome.
5. 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.
