Joints of Upper Limb Flashcards
What are the joints of the pectoral gridle
- sternoclavicular joint
- Acromioclavicular joint
- glenohumeral joint
- elbow joint
- proximal radio ulnar joint
- distal radio ulnar joint
- wrist
what type of joint is the sternoclavicular joint
saddle type of synovial joint
what kind of movement does the sternoclavicular joint have
has a somewhat similar range of ball and socket BUT IS NOT THIS JOINT
BECAUSE it doesnt have a axial rotation
what part of the sternoclavicular joint allows for motion
the articular disk allows for hinge like fx
what kind of capsule is the sternoclavicular joint
complete capsule
what kind of ligaments doe the sternoclavicular joint have
- anterior
- posterior
- interclavicular ligament
- costoclavicular ligament
what degree of motion does the sternoclavicular joint have
can have 15 to 45 degrees of movement anteriorly =15 posterioryly=15 superiorly =45 inferiorly=5
what supplies the sternoclavicular joint with blood
- internal thoracic a.
- suprascapular a
what nerves supply the sternoclavicular joint
- medial supraclavicular n ( medial intermediate and lateral branches )
- nerve to subclavius
what type of joint is the acromioclavicular joint
plane type synovial
what kind of movement does the acromioclavicular joint have
gliding, foration of scapula on clavicle from the articular disc
what kind of capsule does the acromioclavicular joint have
losse joint capsule that can often disloacte in should separation
what ligaments does the acromioclavicular joint have
- acromioclavicular
- coracoacromia
- coracoclavicular
what are the 2 heads of the coracoclavicular ligament
- trapeziod
- conoid
what supply’s the acromioclavicular joint with blood
- suprascapular a
- thoracoacromial a.
what nerves supply the acromioclavicular joint
- lateral supraclavicular n
- lateral pectoral n
- axillary n
What type of joint is the glenohumeral joint
ball and socket joint
more motion and less stability
what kind of capsule is the glenohumeral joint
- lax inferior in resting postion
- long head bicep tendon in capsule
what are the ligaments of the glenohumeral joint
superior middle inferior -coracohumeral ligament coracoacromial arch
where can the ligaments of the glenohumeral joint be found
from glenoid fossa to anatomical neck and they reinforce the joint capsule anteriorly
what is the transerse humeral ligament of the glenohumeral joint
spans the tow tubercles and hold the long head of the biceps down
where can the corahumeral ligament of the glenohumeral joint be found
corocoid process to greater tubercle
where can the coracoacromial arch of the glenohumeral joint be found
coracoid process, acromion, coracoacromial ligament
