wound healing and regeneration

What is the goal of the repair process?

• To restore the tissue to its original state

• To create scar tissue

• To prevent inflammation

• To cause more damage

Which cells play important roles in supporting inflammation, cell migration, and angiogenesis during wound healing?

• Neurons and muscle cells

• Keratinocytes and fibroblasts

• Red blood cells and platelets

• Bacteria and viruses

What is the primary function of wound healing?

• To create scar tissue

• To restore the protective epithelial barrier

• To increase fluid loss

• To prevent cell migration

What are the overlapping phases involved in tissue reconstitution during wound healing?

• Inflammation, fibrosis, scarring, healing

• Hemostasis, proliferation, remodeling, regeneration

• Proliferation, angiogenesis, fibrosis, remodeling

• Hemostasis, inflammation, proliferation, remodeling

Which phase of wound healing involves the release of platelet-derived growth factors and other inflammatory mediators?

• Inflammation

• Hemostasis

• Remodeling

• Proliferation

What is the function of growth factors in wound healing?

• To prevent cell division

• To decrease cell entry in the cell cycle

• To inhibit matrix production

• To activate transcription of coordinating genes

Which type of cells are capable of undergoing rapid division with appropriate stimulation?

• Labile cells

• Stable cells

• Fibroblasts

• Permanent cells

What is the function of the extracellular matrix (ECM) in tissue repair?

• To provide turgor and minerals to tissues

• To secrete growth factors

• To inhibit cell migration

• To prevent cell-cell interactions

What is the appearance of granulation tissue during the proliferative phase of wound healing?

• Dark red and dry

• Yellow and flaky

• Soft, moist, and bumpy

• Hard and smooth

What is the role of fibroblasts in tissue repair?

• To secrete growth factors

• To inhibit cell migration

• To synthesize collagen and extracellular matrix components

• To prevent inflammation
