joints Flashcards
synarthrotic or fibrous
no movement
example of synarthrotic joint
sutures of skull
teeth
ampiarthrotic joint or cartilaginous
slightly moving
examples of ampiarthrotic joint
6 of them
vertebrae growth plates coraclavicular joint tibiofibular joint symphysis pubis costochondral joints
diarthrotic
freely moving
synovial capsule
encases the joint
synivial membrane
lines the capsule that encases the joint
hyaline cartilage
covers articular surfaces of bones
fibrocartilage
found in the knee on articuar surfaces of bones in joint
irregular joint
- planar movement
- nonaxial 0 DF
- gliding movement
examples of irregular joint
carpal and tarsal joint
hinge joint
- uniaxial
- sagittal plane movement
- felxion and extension
examples of hinge joint
- elbow
- knee
- interphalyngeal joints
pivot joint
- uniaxial
- rotation
examples of pivot joint
atlas-axis joint
radio ulnar joint
condyloid joints
- biaxial 2 DF
- flexion/extension
- abduction/adduction
- circumduction
examples of condyloid joints
wrist
metacarpophalangeal
ankle
metatarsalphalangeal
saddle joint
- biaxial 2DF
- like condlyoid joint but more range of motion
examples of saddle joint
carpometacarpal joint of first digit
ball and socket joint
- triaxial 3DF
- flexion/extension
- abduction/adduction
- circumduction
- horizontal abduction/adduction
- rotation
- relys on stability from other tissues
examples of ball and socket
hip and shoulder
what happens as you increase joint stability
- decrease risk of injury
- decrease ROM
definition of joint stability
resistance to displacement
5 factors of joint stability
- ligaments
- shape of bony structure
- muscles
- fascia and skin
- atmospheric pressure
7 factors affecting ROM
- shape of bony structure
- ligaments
- muscles
- body build
- gender
- heredity
- level of fitness and exercise habits
what is the dominant factor that will determine joint stability and ROM
muscle function
