1

three stages of healing

inflammation
proliferation (including epithelialization)
remodeling

2

which stages are the repair stages

proliferation and remodeling

3

lymphatic system
-responsibilities
-passive processes

responsibilities
-pick-up
-transport
passive processes
-no pressure like blood pressure
-vessel walls do not contract
-highly effected by external forces

4

role of therapeutic modalities/exercise on the lymphatic system

increasing lymphatic pick-up = promote healing
ways to promote healing speed
-muscular contraction
-passive ROM
-massage
-compression

5

keloid

a growth of extra scar tissue that is left over after an injury heals
lymphatic system does not clean up all the free protein

6

reconstitution

the replacement of damaged cells with identical cells

7

perfect vs. imperfect reconstitution

perfect: no evidence of damage remaining
imperfect: scar tissue remaining

8

cells that use reconstitution

cells with a high turnover rate
-skin cells
-liver cells

9

replacement

the replacement of injured cells with simpler cells

10

cells that use replacement

muscle tissue
conncetive tissue
CNS tissue

11

primary union

small cut
fills and heals very rapidly

12

secondary union

large gap or hole
repalcement is much slower and leaves a bigger scar

13

epithelialization

the process of developing a membranous tissue covering over exposed tissue or organs

14

function of epithelialization

superficial abrasion or blister
-majority of all healing is epithelialization
severe injuries
-protects the body from assault by outside organisms as the wound heals

15

angiogenesis

formation of new blood vessels
part of the proliferation phase

16

capillary budding

primary mechanism of the vascular phase of the repair process

17

capillary arcade

network of capillary arches
-adjacent capillary buds migrate toward one another, meet, form together, and create the capillary arch

18

collagen

fibrous protein found in all types of connective tissue (ligaments, tendons, scar tissue)

19

collagenization

manufacturing and laying down of collagen in the wound

20

type 3 collagen

initial strands arranged haphazardly within damaged tissue
2-4 days after injury onset

21

type 1 collagen

replaces type 3
aligns in parallel fashion
around day 14

22

tensile strength

amount of force damaged tissue can take before breaking
-depends on collagen type

23

exercise role in collagen structuring

stimulates circulation (increases oxygen flow) which aids healing tissue and collagen restructuring
-provides lines of force which guide collagen restructuring

24

two phases of remodeling

contraction
restructuring

25

contraction

collapsing of capillary arcade
compressed by surrounding collagen

26

restructuring

collagen is restructured
scar is more compact/concave
gives scar greater strength

27

myofibroblasts

cell appears between fibroblast and a smooth muscle cell

28

wound contraction

pulls the sides of the wound together to close it

29

exercise role in remodeling

helps align collagen fibers into parallel lines in line with the lines of force
final phase of wound healing
stimulates circulation and tissue healing

30

nutrition role in remodeling

vitamins are essential to healing, along with trace elements
