Phases of Wound Healing Double Continued

Question 1

When does the process of contraction stop/ terminate? (3)

Answer 1

1. Contact inhibition
2. Increased skin tension
3. Unhealthy wound

Question 2

Scar tissue can cause contractures which limit mobility especially near joints. What is an effect of this condition?

Answer 2

Muscle Atrophy

Question 3

What is the goal of remodeling?

Answer 3

Collagen equilibrium

Question 4

How is collagen equilibrium achieved during the remodeling process?

Answer 4

Collagenolysis and collagen production (production)

Question 5

Three stages of the remodeling or maturation phase of wound healing

Answer 5

1. Collagen equilibrium
2. Decreased cellularity (Fibroblasts/ capillaries)
3. Returning to normal (non-functional scar)

Question 6

Why is there decreased cellularity during the remodeling phase?

Answer 6

Fibroblasts and capillaries that are no longer needed are gotten rid of

Question 7

During the remodeling phase, wounds return to as normal as possible. In mammals this almost always includes what?

Answer 7

Non functional scar tissue (except for bone and epithelial tissue, and somewhat bladder)

Question 8

The Maturation Phase of wound healing is also known as _____________________________

Answer 8

Remodeling
