Q

What makes up ones flexibility?

A

JROM Joint ROM

MF Muscle Flexibility

1
Q

Define Flexibility

A

The ROM available in a joint

2
Q

Static Flexibility is

A

The measured ROM available about a joint or series of joints

3
Q

Identify 2 Extracellular Fibers that play a significant role.

A

Collagen and Elastin

4
Q

Dynamic Flexibility is

A

A measure of the resistance

or series of joints.

5
Q

The load bearing of collagen s dependent on 3 properties that establish its Collagen Fiber Suspension Bridge?

A

Material Properties
Size (areaXlength)
Organization

6
Q

Describe the formation of a tendon by identifying the “tendon hierarchy” figure 13-5

A
Tendon (whole)  with reticular membrane
Fasicle waveform of crimp structure
Fibril fibroblasts
Subfibril
Microfibril 3.5 nm
Tropocollagen
7
Q

What is Ground Substance used for?

A

A viscous gel that serves to provide lubrication and space between the collagen fibers at intercept points where they cross.

8
Q

What is ground substance made of?

A

GAG Glycosaminoglycans

Sugars and proteins

9
Q

3 mechanical properties of connective tissue.

A

Elongation
Viscoelasticity
Plasticity

10
Q

3 physical properties of connective tissue.

A

Force Relaxation
Creep
Hysteresis

11
Q

What are the 4 zones of stress strain curve

A

Toe: elastic
Linear: 3 physical 3 mechanical
Primary Failure: visco plastic force relax creep
Complete Failure: complete fracture

12
Q

What are the 6 anatomical elements that are possible contributors to muscle stiffness (or resistance to deformation)?

A

1 Adhesion of 1 fibril to another between muscle
2 The epimysium
3 Perimysium and Endomysium
4 Sarcolemma
5 Contractile elements within the muscle fiber
6 The associated tendons and their insertion

14
Q

what is epimysium

A

is a layer of connective tissue, which ensheaths the entire muscle

15
Q

Collagen

A

provides skeletal structure that holds C.T. together, enabling the tissue to resist mechanical forces and deformation

16
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

31
Q

What is collagen

A

Fibrous protein
provides skeletal structure that holds

32
Q

What is elastin

A

Assists the recovery of a tissue from deformation
