Q1.
A researcher observes that a particular epithelial tissue has a basal lamina that is
unusually thick and contains type VII collagen anchoring fibrils. In which location is this
tissue most likely found?
A. Lining of the small intestine B. Epidermis of the skin
C. Endothelium of blood vessels D. Respiratory bronchioles
Correct: B - Epidermis of the skin
Rationale:The epidermis has a thick basement membrane with anchoring fibrils (type VII
collagen) that secure it to the dermis, especially in areas of mechanical stress. Other epithelia
have a thinner basal lamina lacking such prominent anchoring fibrils.
Why the other answers are wrong:
A. Intestinal epithelium has a thin basal lamina without prominent type VII collagen anchoring
fibrils.
C. Endothelium has a delicate basal lamina, not a thick one with anchoring fibrils.
D. Respiratory bronchiolar epithelium has a thin basal lamina; type VII collagen is not a
hallmark.

Q2.
In a patient with a deep partial-thickness burn, pain sensation is preserved. Which of the
following best explains this clinical finding?
A. The burn has destroyed the dermal nerve B. The burn has damaged the epidermis but
endings but the epidermal nociceptors the dermal nerve endings are still functional.
remain intact.
C. The burn has caused edema that D. The burn has injured the subcutaneous
compresses nerve fibers, leading to layer, where pain receptors are most
hyperalgesia. concentrated.
Correct: B - The burn has damaged the epidermis but the dermal nerve endings are still
functional.
Rationale:Deep partial-thickness burns destroy the epidermis but spare the dermis, where
most nociceptors reside, so pain is preserved. Full-thickness burns destroy the dermis and
thus eliminate pain sensation.
Why the other answers are wrong:
A. Epidermal nociceptors are sparse; pain in partial-thickness burns comes from dermal nerve

, Section A - Integumentary System
endings.
C. Edema may cause pain but does not explain the specific preservation of sensation in partial-thickness burns.
D. Subcutaneous layer has fewer pain receptors; the key is the dermis.

Q3.
A 30-year-old individual sustains a fracture that heals without callus formation. Which
type of fracture is most consistent with this outcome?
A. Comminuted fracture of the femur B. Greenstick fracture of the radius
C. Stable, non-displaced fracture of the D. Pathologic fracture due to osteosarcoma
fibula
Correct: C - Stable, non-displaced fracture of the fibula
Rationale:A stable, non-displaced fracture may heal by direct (primary) bone healing without
a visible callus, especially if the fracture ends are closely apposed and immobilized. Other
fracture types typically involve callus formation.
Why the other answers are wrong:
A. Comminuted fractures usually heal by secondary intention with callus formation.
B. Greenstick fractures, common in children, typically heal with callus formation.
D. Pathologic fractures often heal with callus unless the tumor interferes, but callus is still
typical.

Q4.
Which of the following best describes the biomechanical consequence of a torn anterior
cruciate ligament (ACL) on the knee joint?
A. Increased anterior translation of the tibia B. Increased posterior translation of the tibia
on the femur on the femur
C. Increased lateral rotation of the tibia D. Increased medial rotation of the femur
during flexion during extension
Correct: A - Increased anterior translation of the tibia on the femur
Rationale:The ACL prevents anterior displacement of the tibia relative to the femur. Its
rupture allows excessive anterior translation, which is the basis of the anterior drawer test.
Why the other answers are wrong:
B. Posterior translation is prevented by the posterior cruciate ligament, not the ACL.
C. Lateral rotation is primarily controlled by collateral ligaments and menisci, not the ACL.
D. Medial rotation of the femur is not directly prevented by the ACL.
