1

CT is considered what type of substance

Colloidal

2

What is heat or pressure that changes ground substance from a dense gel to o more liquid state

Thixotropy

3

What is the piezoelectric effect

The ability of an object to produce a voltage after a mechanical compression stress

4

True or False:
Piezo electricity exists in crystals

True

5

What does CT behave as in the piezoelectric model

A crystal

6

What influences fibroblast and fibroclast activity

Charge

7

What is the ability of a substance to resist flow

Viscosity

8

What is the ability of a substance to rebound from deformation

Elasticity

9

What is the region that represents "setting" of the structure being tested including taking up slack

Toe region

10

Which zone does the deformation usually result in permanent deformation

Plastic zone

11

Which zone is deformation reversible

Elastic zone

12

What is the point of the stress strain curve called where after attaining ultimate stress, the tissue begins to fail

Neck

13

What is the point of the stress strain curve where sudden decrease in stress while strain continues to rise

Failure point

14

What is happening at the neck point of the stress strain curve

Initially microfailure and tissues narrow (necking)

15

What does the sudden decrease at the failure point mean

Substance of the material has begun to fail (tear)

16

What is the stress being lower during unloading for any given strain that occurs during loading

Discrepancy

17

What ia the difference in strain between loading and unloading called

Hysteresis

18

What does hysteresis represent

Energy lost during the test

19

True or False:
After repeated loading the stress strain curve looks identical yet starts at a new point

True

20

What is creep

Applying a constant load to a structure to lengthen it

21

How do you achieve a greater length increase in tissue using creep

Longer duration and less load

22

How is energy lost in a hysteresis loop

In the form of heat

23

What will cause a stiffer substance with higher loading rates to fail

Higher stresses and lower strains

24

What will cause a less stiff substance at higher temperatures to fail

Lower stresses and higher strains

25

Does heating tissue make it easier or harder to induce plastic elongation

Easier

26

What is the response of myofascial tissue to immobilization

Loss of ground substance

27

What are the 3 things that cause ground substance to be lost

1. Loss of glycosaminoglycans and water
2. Loss of interfiber lubrication
3. Loss of interfiber distance

28

What does the loss of ground substance result in

New crosslinks that adhere adjacent collagen fibers together

29

What is the half life of collagen

300-500 days

30

What is the half life of ground substance

1.7-7 days
