What factor affects joint stability related to bony structure shape?
Shape
of the
bony
structure
View source
How does the depth of the acetabulum affect joint stability?
It provides greater protection against
displacement
View source
What is the role of ligaments in joint stability?
They maintain bones in the
correct relationship
View source
How do ligaments check movement in joints?
They resist movements beyond normal
limits
View source
What type of tissues are ligaments?
Fibrous tissues
View source
What is the role of muscular arrangement in joint stability?
They contribute to stability in
weak joints
View source
Which muscles are part of the rotator cuff?
Subscapularis
,
supraspinatus
,
infraspinatus
,
teres minor
View source
How does fascia vary in the body?
It varies from thin
membranes
to tough tissue
View source
What role does atmospheric pressure play in joint stability?
It mainly affects the
hip joint
View source
How do the shapes of articular surfaces affect range of motion?
More
congruent
surfaces restrain motion
View source
What is the effect of ligaments on joint motion?
They
stabilize
without
limiting
too
much
motion
View source
How does hamstring tightness affect hip flexion?
It acts as an
antagonist
during the motion
View source
Which body types usually have greater flexibility?
Mesomorph
and
ectomorph
View source
How does body build affect flexibility?
Bulk
of tissue can limit certain actions
View source
How do personal exercise habits influence range of motion?
Training for
flexibility
increases range
View source
What factors affect range of motion?
Age
,
heredity
, and
fitness state
View source
How does pelvic tilting relate to hip movement?
It affects the
apparent range of motion
View source
How does the method of joint movement affect range of motion?
Active
and
passive
movements affect ROM
View source
What is a body link?
It extends between two
joint axes
View source
What is the purpose of link systems in the body?
They determine
permitted motion types
View source
What is a kinematic chain?
A combination of
successively
arranged
joints
View source
What are the two types of kinematic chains?
Open
and
closed
kinematic chains
View source
How does an open kinematic chain differ from a closed one?
Distal segment
is free in space
View source
What happens when a joint in a kinematic chain is restricted?
Distal
segments lose
versatility
View source
What are the factors affecting joint stability?
Shape of
bony structure
Ligaments
arrangement
Muscular
arrangement
Fascia
Atmospheric pressure
View source
What are the factors affecting range of motion?
Shape of
articular surfaces
Ligaments and muscles' restraining effects
Body
build
Personal
exercise habits
Current state of
physical fitness
Age
Heredity
View source
What is the relationship between body link systems and kinematic chains?
Body links extend between
joint axes
Kinematic chains consist of
interconnected joints
Both determine
motion types
and calculations
