#1
What is the primary function of platelets in the wound healing process?
Initiate blood clotting
ExplanationPlatelets initiate the blood clotting process to stop bleeding.
#2
During the inflammatory phase of wound healing, which cells are primarily responsible for phagocytosis of debris and bacteria?
Neutrophils
ExplanationNeutrophils phagocytose debris and bacteria during the inflammatory phase.
#3
What is the term for a wound that heals by first intention, with minimal tissue loss and a well-approximated edge?
Primary intention
ExplanationPrimary intention healing involves minimal tissue loss and well-approximated wound edges.
#4
Which cell type is responsible for producing collagen during the proliferative phase of wound healing?
Fibroblasts
ExplanationFibroblasts produce collagen during the proliferative phase of wound healing.
#5
What is the primary function of fibroblasts in wound healing?
Produce collagen
ExplanationFibroblasts play a primary role in producing collagen during wound healing.
#6
Which phase of wound healing involves the formation of granulation tissue and angiogenesis?
Proliferative phase
ExplanationGranulation tissue forms, and new blood vessels (angiogenesis) develop.
#7
In wound healing, what is the purpose of the remodeling phase?
Remove dead cells and debris
ExplanationRemodeling phase removes dead cells and debris, enhancing tissue strength.
#8
What is the main purpose of sutures or staples in wound closure?
To approximate wound edges
ExplanationSutures/staples approximate wound edges, aiding healing and reducing scarring.
#9
Which vitamin is essential for collagen synthesis and wound healing?
Vitamin C
ExplanationVitamin C is crucial for collagen synthesis and overall wound healing.
#10
In wound healing, what is the primary role of myofibroblasts during the proliferative phase?
Contract wound edges
ExplanationMyofibroblasts contract wound edges to reduce size during the proliferative phase.
#11
Which growth factor plays a crucial role in promoting cell proliferation and migration during wound healing?
Fibroblast Growth Factor (FGF)
ExplanationFGF promotes cell proliferation and migration in wound healing.
#12
Which type of collagen is primarily responsible for providing strength to the wound during the maturation phase?
Collagen Type I
ExplanationCollagen Type I provides strength to the wound during maturation.
#13
What is the significance of the tensile strength of a healing wound?
It measures the resistance to deformation
ExplanationTensile strength measures the resistance of a healing wound to deformation.
#14
Which enzyme is involved in breaking down fibrin during the clot removal process in wound healing?
Plasmin
ExplanationPlasmin is responsible for breaking down fibrin during clot removal in wound healing.
#15
Which factor contributes to impaired wound healing in individuals with diabetes?
Impaired microcirculation
ExplanationImpaired microcirculation contributes to impaired wound healing in diabetes.
