Lecture 13 Flashcards
Mobility Vs. Immobility
Things that can affect balance(6)
1) Disease
2) Injury
3) Pain
4) Physical development (e.g. age)
5) Life changes (e.g. pregnancy)
6) Some medications
why do some self-impose activity restrictions when their balance is impaired?
due to a fear of falling; contributes to mobility issues
when is people’s center of gravity at most of the time?
@ 55%-57% standing height in the midline
the greater the (BLANK), the greater the friction
Surface area
The force exerted against the skin while the skin remains stationary and the bony structures move is called (BLANK)
shear
what does body alignment mean?
the individuals center of gravity is stable
What is in bones that make them rigid(firm)?
Inorganic salts (Calcium and phosphate)
what are the functions of the skeletal system(4)?
1) Provides attachment points for muscles and ligaments
2) Protects vital organs
3) aids in calcium regulation
4) Provides leverage for mobility
What are joints?
functional junctions between bones
what types of joints are associated with mobility(3)?
1) cartilaginous
2) Fibrous
3) Synovial
Each joint is classified according to it’s(2):
1) Structure
2) Degree of mobility
what are ligaments?
bands of fibrous tissue that binds joints together and connect bones to cartilage
What is the function of ligaments(2)?
1) Joint flexibility
2) Support
what is the purpose of tendons?
to connect muscle to bone
what are the characteristics of tendons(3)?
1) Strong
2) Flexible
3) Inelastic
what is cartilage?
Avascular connective tissue
where is cartilage found(6)?
1) Joints
2) Thorax
3) Trachea
4) Larynx
5) Nose
6) ears
the characteristics of cartilage changes with…
age
which system regulates movement and posture?
The nervous system
Postural abnormalities can cause:
pain, impair alignment or mobility, or both
when should you observe body alignment and ROM?
during assessment
when should you observe body alignment and ROM?
during assessment
Damage to any component of the CNS that regulates voluntary movement results in impaired(3):
1) Body alignment
2) Balance
3) Mobility
Where is the motor strip located?
back of frontal lobe
