Q

Elastin

A

assists in the recovery of a tissue from deformation

17
Q

Elasticity

A

spring-like behavior where elongation, which is produced by tensile load, is recovered after the load is removed

18
Q

Viscoelasticity

A

allows slow deformation with an imperfect recovery once the deforming force as been removed. The recovery is the result of the elasticity and the imperfection is the result of viscosity. Not permanent.

19
Q

Plasticity

A

permits permanent plastic defomation

20
Q

Force relaxation

A

the decrease in the amount of force required to maintain a tissue at a set amount of displacement or deformation over time. The rate at which the force is applied will affect the resulting relaxation of the tissue

21
Q

Creep response

A

ability of the tissue to deform over time while the constant force is being applied

22
Q

Hysteresis response

A

the amount of relaxation a tissue has undergone during any single cycle of deformation and relaxation

23
Q

Perimysium

A

is a sheath of connective tissue that groups muscle fibers into bundles (anywhere between 10 to 100 or more) or fascicles.

24
Q

Endomysium

A

is a wispy layer of areolar connective tissue that ensheaths each individual muscle fiber. It also contains capillaries and nerves. It overlies the muscle fiber’s cell

25
Q

Sarcolemma

A

also called the myolemma, is the cell membrane of a striated muscle fiber cell

26
Q

Other aspects relating to flexibility

A

Mobility
Stability
Controlled Mobility
Skill

27
Q

Gama Bias

A

28
Q

JROM

A

Ability of periarticular connective tissue to deform

Joint Arthrokinematics

29
Q

Muscle flexibility

A 
Ability of muscle to lengthen
Neuromuscular component (GTO & muscle spindle)
30
Q

*Test Static vs. Dynamic flexibility

A

Static - the measured ROM available about a joint or series of joints
Dynamic- the measure of resistance to active motion about a joint or series of joints
