Modalities Ch. 7

Question 1

three stages of healing

Answer 1

inflammation
proliferation (including epithelialization)
remodeling

Question 2

which stages are the repair stages

Answer 2

proliferation and remodeling

Question 3

lymphatic system

• responsibilities
• passive processes

Answer 3

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

Question 4

role of therapeutic modalities/exercise on the lymphatic system

Answer 4

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

Question 5

keloid

Answer 5

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

Question 6

reconstitution

Answer 6

the replacement of damaged cells with identical cells

Question 7

perfect vs. imperfect reconstitution

Answer 7

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

Question 8

cells that use reconstitution

Answer 8

cells with a high turnover rate

• skin cells
• liver cells

Question 9

replacement

Answer 9

the replacement of injured cells with simpler cells

Question 10

cells that use replacement

Answer 10

muscle tissue
conncetive tissue
CNS tissue

Question 11

primary union

Answer 11

small cut

fills and heals very rapidly

Question 12

secondary union

Answer 12

large gap or hole

repalcement is much slower and leaves a bigger scar

Question 13

epithelialization

Answer 13

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

Question 14

function of epithelialization

Answer 14

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

Question 15

angiogenesis

Answer 15

formation of new blood vessels

part of the proliferation phase

Question 16

capillary budding

Answer 16

primary mechanism of the vascular phase of the repair process

Question 17

capillary arcade

Answer 17

network of capillary arches

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

Question 18

collagen

Answer 18

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

Question 19

collagenization

Answer 19

manufacturing and laying down of collagen in the wound

Question 20

type 3 collagen

Answer 20

initial strands arranged haphazardly within damaged tissue

2-4 days after injury onset

Question 21

type 1 collagen

Answer 21

replaces type 3
aligns in parallel fashion
around day 14

Question 22

tensile strength

Answer 22

amount of force damaged tissue can take before breaking

-depends on collagen type

Question 23

exercise role in collagen structuring

Answer 23

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

Question 24

two phases of remodeling

Answer 24

contraction

restructuring

Question 25

contraction

Answer 25

collapsing of capillary arcade

compressed by surrounding collagen

Question 26

restructuring

Answer 26

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

Question 27

myofibroblasts

Answer 27

cell appears between fibroblast and a smooth muscle cell

Question 28

wound contraction

Answer 28

pulls the sides of the wound together to close it

Question 29

exercise role in remodeling

Answer 29

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

Question 30

nutrition role in remodeling

Answer 30

vitamins are essential to healing, along with trace elements
