- A. Both of the above
- B. Secondary union
- C. Primary union
- D. None of the above
Explanation: Primary bony union may occur by direct healing with medullary or endosteal bone formation and little or no periosteal callus.
Correct answer: Primary union- A. Infection
- B. Cortisol
- C. Foreign Bodies
- D. All of the aboveConsult Online Doctors
Explanation: Infection, glucocorticoids such as cortisol, and retained foreign bodies all delay healing by sustaining inflammation or suppressing…
Correct answer: All of the aboveConsult Online Doctors- A. Implantation cyst
- B. Keloid
- C. Wound dehiscence
- D. Cicatrisation
Explanation: Entrapped epithelial cells can continue to proliferate and form an implantation cyst after wound closure.
Correct answer: Implantation cyst- A. Cicatrisation
- B. Primary healing
- C. Secondary healing
- D. RegenerationConsult Injury Lawyers
Explanation: Large wounds with tissue loss cannot have their edges directly approximated, so they heal by secondary intention with abundant granulation…
Correct answer: Secondary healing- A. Giant cells
- B. Fibroblasts
- C. Endothelial cells
- D. B & C
Explanation: Granulation tissue is made mainly of proliferating capillaries lined by endothelial cells and fibroblasts producing extracellular matrix.
Correct answer: B & C- A. Fibroblasts
- B. Myofibroblasts
- C. Vitamin C
- D. Vitamin D
Explanation: Fibroblasts produce collagen, myofibroblasts cause wound contraction, and vitamin C is required for collagen hydroxylation and strength.
Correct answer: Vitamin D- A. 1
- B. 2
- C. 0.5
- D. 5
Explanation: Peripheral axons generally regenerate at approximately 1 mm per day, provided the connective-tissue pathway and neuron remain viable.
Correct answer: 1- A. Remodeling of bone
- B. Formation of fibrous joint or pseudoarthrosis
- C. Formation of blood clot
- D. Formation of procallus or osseous cells
Explanation: A fibrous joint or pseudoarthrosis represents failure of bony union, whereas a clot, procallus, and subsequent remodeling are normal…
Correct answer: Formation of fibrous joint or pseudoarthrosis- A. Hormones
- B. Blood supply
- C. Growth factors
- D. Collagen
Explanation: Collagen provides the tensile strength of a healing wound, with strength increasing as collagen is deposited and remodelled.
Correct answer: Collagen50. All of the following events are common to primary and secondary wound healing except_____________?
- A. Wound contraction
- B. Inflammatory response
- C. Epithelial changes
- D. Formation of blood clot
Explanation: Wound contraction is prominent in secondary intention because the larger tissue defect requires myofibroblasts to pull the edges together.
Correct answer: Wound contraction- A. Secondary intention
- B. Primary intention
- C. Cicatrisation
- D. All of the above
Explanation: A clean surgical wound whose edges are closely approximated with sutures heals by primary intention, with minimal tissue loss…
Correct answer: Primary intention- A. Coagulative necrosis
- B. Caesous necrosis
- C. Fibrinoid necrosis
- D. Fatty necrosis
Explanation: Fibrinoid necrosis is a smudgy, intensely eosinophilic vascular deposit formed from necrotic tissue mixed with immune complexes…
Correct answer: Fibrinoid necrosis- A. Midline lethal granuloma
- B. Sarcoidosis
- C. Leprosy
- D. Tuberculosis
Explanation: Caseous necrosis is the characteristic necrosis of tuberculosis, producing a soft, cheese-like appearance within granulomas.
Correct answer: Tuberculosis
