Tissue repair Flashcards
1
Q
What is regeneration?
A
- Same tissue replaces destroyes tissue
- The original function is restored
2
Q
What is fibrosis?
A
- Connective tissue replaces destroyed tissue
- The original function is lost
3
Q
Step 1: Inflammation
A
- Blood vessel dialates; becomes permiable
- Blood clots on external surface
4
Q
Step 2: Organization
A
- Blood clot is replaced with granulation tissue
- Epithelium regenerates
- Fibroblast produces collagen to bridge gap
- Debri gets phagocytized
5
Q
Step 3: Regeneration
A
- Scab falls off
- Epithelium thickens; resembles adjacent tissue
- Potential for scar tissue gets layed down
6
Q
Tissues w/ good regeneration
A
- bone
- areolar
- dense irregular
- c.t
- blood forming
- epithelium
7
Q
Tissues w/ moderate regeneration
A
- smooth muscle
- cartilage
8
Q
Tissues w/ weak regeneration
A
- Skeletal muscle
- Cartilage
9
Q
Tissues w/ no regenerational capacity
A
- Cardiac muscle
- Nervous tissue
