Morphology of fibrocytic disease:
- A. Apocrine metaplasia
- B. Proliferation of ductules
- C. Epithelial hyperplasia
- D. Giant cell
Correct Answer: C
Rationale: The correct answer is C: Epithelial hyperplasia. Fibrocytic disease involves nonproliferative and proliferative fibrocystic changes in the breast tissue. Epithelial hyperplasia is a common proliferative change seen in fibrocystic disease, characterized by increased number of epithelial cells in the ducts and lobules. Apocrine metaplasia, choice A, is another common change in fibrocystic disease but is not specific to morphology. Proliferation of ductules, choice B, is not a characteristic feature of fibrocystic disease. Giant cells, choice D, are not typically associated with fibrocystic changes.

The ________ is an ovoviviparous animal.
- A. Basking shark
- B. Bonobo
- C. Blue shark
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Basking shark. Ovoviviparous animals are those that produce eggs that hatch inside the mother's body, giving birth to live young. Basking sharks exhibit this reproductive strategy, making them ovoviviparous.
Explanation of incorrect choices:
B: Bonobos are primates and give birth to live young, but they are not ovoviviparous.
C: Blue sharks give birth to live young as well, but they are not ovoviviparous.
D: "None of the above" is incorrect as the basking shark is indeed an ovoviviparous animal, making it the correct answer.
Uterine tubes are otherwise called as
- A. Vas deferens
- B. Epididymis
- C. Fallopian tubes
- D. Vagina
Correct Answer: C
Rationale: The correct answer is C: Fallopian tubes. These tubes are also known as uterine tubes because they connect the ovaries to the uterus, allowing eggs to travel from the ovaries to the uterus. The other choices are incorrect because:
A: Vas deferens is a tube that carries sperm from the epididymis to the urethra in males.
B: Epididymis is a coiled tube located on the back of each testicle where sperm mature.
D: Vagina is the muscular tube that connects the cervix to the external genitalia in females.
Breastbone is otherwise known as
- A. Xiphoid process
- B. Sternum
- C. Clavicle
- D. Coracoid process
Correct Answer: B
Rationale: The correct answer is B: Sternum. The sternum is commonly referred to as the breastbone because it is a flat bone located in the center of the chest. It connects to the rib cage and helps protect vital organs such as the heart and lungs. The xiphoid process (choice A) is the lower part of the sternum, the clavicle (choice C) is the collarbone, and the coracoid process (choice D) is a projection on the scapula. Therefore, the sternum is the most appropriate term for the breastbone.
Which of these is not a function of testosterone?
- A. loss of body hair
- B. thickening of the larynx
- C. anabolism of skeletal muscle
- D. thickening of bones
Correct Answer: A
Rationale: The correct answer is A, loss of body hair. Testosterone is responsible for thickening of the larynx, anabolism of skeletal muscle, and thickening of bones. It promotes growth and development of male secondary sexual characteristics, such as increased body hair. Therefore, loss of body hair is not a function of testosterone. Choice B, thickening of the larynx, is correct because testosterone contributes to the deepening of the voice by thickening the vocal cords. Choice C, anabolism of skeletal muscle, is correct as testosterone enhances protein synthesis in muscles, leading to muscle growth. Choice D, thickening of bones, is correct because testosterone promotes bone growth and mineralization.
