Inflammatory Process: Concepts of Soft Tissue Healing

Question 1

What are the 3 phases of healing?

Answer 1

1. Inflammation
2. Proliferation
3. Remodeling

Question 2

What are the 4 phases of tissue healing?

Answer 2

1. Hemostasis: Stopping of blood (the storm)
2. Inflammatory Response: (immediate aftermath of storm)
3. Proliferation/fibroblastic (clean up and repair or connective tissue)
4. Remodeling/maturation phase (restoration)

Question 3

What is Hemostasis and when does it occur?

Answer 3

1. Occurs during the initial reaction to injury.
2. Def: Stoppage of blood flow to the area.
3. Vasoconstriction.
4. Initiation of histamine
   - Increases cell permeability (ability of substance to pass through it.)
   - Allows white blood cells to enter

Question 4

What are platelets?

Answer 4

1. Cell fragments in our blood that form clots to stop or prevent bleeding.
2. Cytokines: Regulate immune response.
3. Release phospholipids: Stimulating clot formation.

Question 5

What is the inflammatory response?

Answer 5

1. Needed for healing to occur
