Lecture 13 Flashcards
Things that can affect balance
1) Disease
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
What are joints?
functional junctions between bones
what are the three classifications of joints(3)?
1) cartilaginous
Each joint is classified according to it’s(2):
1) Structure
what are ligaments?
bands of fibrous tissue that binds joints together and connect bones to cartilage
What is the function of ligaments(2)?
Connect bones together and provide:
what is the purpose of tendons?
to connect muscle to bone
what are the characteristics of tendons(3)?
1) Strong
what is cartilage?
Avascular connective tissue
where is cartilage found(6)?
1) Joints
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
Damage to any component of the CNS that regulates voluntary movement results in impaired(3):
1) Body alignment
Where is the motor strip located?
back of frontal lobe
What kinds of things can damage the brain(3)?
1) Stroke (CVA)
