1. The placenta is developed from which part of the trophoblast?

• A. Chorionic Frondosum
• B. Anchoring Villi
• C. Chorionic Laeve
• D. Body Stalk

Correct answer: A

Rationale: The correct answer is A: Chorionic Frondosum. The placenta is developed from the chorionic frondosum part of the trophoblast. This structure gives rise to the fetal part of the placenta. Choices B, C, and D are incorrect. Anchoring Villi are projections from the chorionic plate that attach the placenta to the uterine wall. Chorionic Laeve refers to the smooth chorion that covers the fetal surface of the placenta. The Body Stalk is a structure that connects the early embryo to the trophoblastic pole of the blastocyst.

2. What is a characteristic of threatening abortion?

• A. Os open.
• B. Firm contracted uterus.
• C. Heavy bleeding.
• D. Severe cramping.

Correct answer: B

Rationale: Threatening abortion is characterized by a firm contracted uterus with an open os. This presentation indicates a risk of miscarriage. Choice A ('Os open') is not specific enough and does not fully describe the condition. Choices C ('Heavy bleeding') and D ('Severe cramping') can also be present in threatening abortion, but the primary characteristic is a firm contracted uterus with an open os.

3. Through which arteries does the blood supply to the external genitalia primarily occur?

• A. Femoral arteries
• B. Inguinal arteries
• C. Pudendal arteries
• D. Internal iliac arteries

Correct answer: C

Rationale: The correct answer is C: Pudendal arteries. The pudendal arteries are responsible for supplying blood to the external genitalia. These arteries specifically provide blood flow to the perineum, including the external genitalia. Choice A, Femoral arteries, are not primarily responsible for supplying blood to the external genitalia. Choice B, Inguinal arteries, do not supply blood directly to the external genitalia. Choice D, Internal iliac arteries, are not the main suppliers of blood to the external genitalia.

4. Inevitable abortion is characterized by:

• A. Heavy bleeding.
• B. Open os.
• C. Severe cramping.
• D. Light bleeding.

Correct answer: B

Rationale: Inevitable abortion is characterized by an open os. This condition is associated with heavy bleeding. While severe cramping can be present in inevitable abortion, the key characteristic is the open os, making choice B the correct answer. Choices A and D are incorrect because they do not specifically describe the defining feature of inevitable abortion, which is the open os.

5. The weight of the non-pregnant uterus is approximately ___________grams.

• A. 57
• B. 80
• C. 66
• D. 71

Correct answer: B

Rationale: The correct answer is B: 80. The non-pregnant uterus typically weighs around 80 grams. This weight may vary slightly among individuals, but 80 grams is a commonly accepted average. Choices A, C, and D are incorrect as they do not reflect the typical weight of the non-pregnant uterus. It is important to remember this approximate weight for medical reference and understanding of normal anatomical variations.
