Questions and Answers

What is the role of neutrophils in the inflammation phase?

  • Amplify inflammatory response by release of cytokines, reduce infection by bacterial killing, and debride damaged tissue (correct)
  • Fibroblasts migrate into the wound and synthesize collagen
  • Thrombus formation and reactive vasospasm achieve haemostasis
  • Specialized myofibroblasts containing actin cause wound contraction

What occurs in the immediate phase of haemostasis?

  • Platelets aggregate at the wound and release inflammatory mediators (correct)
  • Fibroblasts migrate into the wound and synthesize collagen
  • Vasodilation and increased capillary permeability allow inflammatory cells to enter wound
  • Reorientation and maturation of collagen fibers increase wound strength

What is the main activity during the proliferation phase?

  • Reorientation and maturation of collagen fibers increase wound strength
  • Vasodilation and increased capillary permeability allow inflammatory cells to enter wound
  • Fibroblasts migrate into the wound and synthesize collagen (correct)
  • Platelets aggregate at the wound and release inflammatory mediators
