8/26 Injury Response Process Flashcards Part 3

Delicate scar tissue consisting of capillaries, collagen, and fibroblasts.

granulation tissue

The framework laid down by fibroblasts during tissue repair.

extracellular matrix

What collagen type appears first in healing?

type 3

What are the characteristics of type 3 colagen?

weak, fragile, and low tensile strength

When does type 3 collagen begin changing to type 1?

5-11 days after injury

Formation of extracellular matrix and collagen framework.

fibroplasia

What are signs of Fibroblastic Remodeling Phase?

decreased swelling, some tenderness, and increasing tissue resistance

When may treatment progress from cold to heat?

when swelling begins to decrease

Examples of thermotherapy.

hydrocollator packs, paraffin baths, warm whirlpools

What is the purpose of electrical stimulation?

promote muscle pumping, assist healing, modulate pain

When does the Maturation Remodeling Phase begin?

3 weeks after injury and may last over a year

What is the primary goal of the Maturation Remodeling Phase?

replace type 3 collagen with type 1 collagen

What is type 1 collagen known for?

greater strength

Law that states bone and soft tissue remodel according to the physical demands and tensile forces placed upon them.

Wolff’s Law

Rupture of cells spills content cuasing cell death.

tissue necrosis
