Which statement about the ovary is not true:
- A. it is a pair organ;
- B. it is a gland with mixed role;
- C. it is oval-shaped;
- D. it is located in the right flank
Correct Answer: D
Rationale: The correct answer is D because the ovary is not located in the right flank; it is located in the lower abdomen. A: The ovary is a pair organ, as there are two ovaries in the female reproductive system. B: The ovary is a gland with mixed roles, producing hormones and releasing eggs. C: The ovary is oval-shaped, which is anatomically correct. Therefore, choice D is incorrect as the ovary is not located in the right flank.

The veins of the ovary can open into:
- A. inferior vena cava;
- B. uterine vein;
- C. renal vein;
- D. internal iliac vein;
Correct Answer: D
Rationale: The correct answer is D: internal iliac vein. The veins of the ovary drain into the ovarian veins, which then connect to the pampiniform plexus, ultimately draining into the internal iliac vein. This pathway allows for the blood from the ovary to be carried back to the heart. The other choices (A, B, C) are incorrect as the ovarian veins do not typically open into the inferior vena cava, uterine vein, or renal vein.
What is line “D” pointing to?
- A. Follicular fluid
- B. Germinal epithelium
- C. Ovarian cortex
- D. Ovarian medulla
Correct Answer: D
Rationale: The correct answer is D: Ovarian medulla. Line "D" is pointing to the inner region of the ovary known as the medulla, which contains blood vessels, nerves, and connective tissue. This is confirmed by the location and characteristics of the structures in that region.
Explanation:
1. Follicular fluid (Choice A) is found within the follicles in the ovarian cortex, not in the medulla.
2. Germinal epithelium (Choice B) is the outermost layer of the ovary, whereas the medulla is located deeper within the ovary.
3. Ovarian cortex (Choice C) is the outer layer of the ovary where follicles develop, while the medulla is the inner region.
In summary, the correct answer is D (Ovarian medulla) as it accurately identifies the inner region of the ovary where blood vessels and connective tissue are located, distinguishing it from the other choices.
The medical term expressing suture of the perineum is ________
- A. cervicography
- B. perineorrhaphy
- C. cervicorrhapy
- D. cervicorrhexis
Correct Answer: B
Rationale: The correct answer is B: perineorrhaphy. "Perineorrhaphy" refers to the surgical suturing of the perineum. The term is derived from "perineum" (the area between the anus and the genitalia) and "rrhaphy" (meaning suture).
A: cervicography - This term refers to a diagnostic procedure involving imaging of the cervix, not related to suturing the perineum.
C: cervicorrhapy - This term does not exist in medical terminology and is not related to suturing the perineum.
D: cervicorrhexis - This term refers to the tearing of the cervix, not the suturing of the perineum.
In summary, perineorrhaphy is the correct term as it specifically refers to suturing the perineum, while the other choices are unrelated to this procedure.
Trabecular bone is otherwise called as
- A. Compact bone
- B. Cortical bone
- C. Spongy bone
- D. None of the abov
Correct Answer: C
Rationale: Trabecular bone, also known as spongy bone, is characterized by its porous structure with trabeculae. It is found at the ends of long bones and inside flat bones. Spongy bone provides structural support and flexibility. Compact bone (A) is dense and forms the outer layer of bones. Cortical bone (B) is synonymous with compact bone. Choice D is incorrect as trabecular bone is specifically known as spongy bone.
A drug is given that affects the initial phases of spermatogenesis to aid in a patient’s infertility complaints. How much time would it take for the effects of this drug to be seen?
- A. 4.6 days
- B. 16 days
- C. 22 days
- D. 86 days
Correct Answer: D
Rationale: The correct answer is D (86 days) because spermatogenesis is a process that takes around 74 days from the initial division of spermatogonia to the release of mature spermatozoa. The drug affecting the initial phases of spermatogenesis would take at least one full cycle of spermatogenesis to show its effects, which is around 74 days. Therefore, it would take approximately 86 days for the effects of the drug to be seen.
Choice A (4.6 days) is too short for spermatogenesis to complete, so the effects of the drug would not be observable in this time frame. Choice B (16 days) and Choice C (22 days) are also insufficient for a full cycle of spermatogenesis to occur, hence the effects of the drug would not be evident within these durations.
