Elasticity

Answer 22

ability to return to normal shape

Question 23

plasticity

Answer 23

ability to change shape and size due to external force

Question 24

Viscosity ( related to ground substance)

Answer 24

ability to resist a load that produces a shear force.

Question 25

viscoelastcity

Answer 25

ability to resist change in shape but unable to completely return to former state after changing shape ( between elastic and plastic region)

Question 26

Mechanical property of flexibility

Answer 26

- Elasticity - plasticity - viscosity - viscoelasticity

myostatic contracture

Answer 28

no specific tissue pathology can be resolved

Question 29

adhesion contracture

Answer 29

Increase in cross bonding and adherence between fibers, loss of mobility

Question 30

Irreversible contracture

Answer 30

permanent loss of extensibility in soft tissue

Question 31

psuedomyostatic contractue

Answer 31

limit of motion due to hypertonicity

Question 36

greatest force in muscle when?

Answer 36

slightly lengthened

Question 37

Is a slower contraction better or worse for muscle strength

Answer 37

better (greater torque - more muscle units)
