- glenohumeral
scapula position - covers what ribs, how far from midline
- ribs 2-7
- approx 2 inches from mid-line
scapula - angles in frontal plane and ant tipping
- 30-40 degrees forward of frontal plane
- 10-20 degrees anterior tipping
motions of the scapula
- elevation/depression
- protraction/retraction
- up and down rot
- ant/post tipping
sternoclavicular joint is what type of joint?

saddle synovial joint

- costoclavicular lig
- interclavicular lig
clavicular motions
- elev/depression
- pro/retraction
- ant/post rotation
acromioclavicular joint - what kind of joint?

plane synovial
2 major ligaments of the acromioclavicular joint
- acromioclavicular lig
- coracoclavicular lig
scapular motions at the acromioclavicular joint
- med/lat rot
- ant/post tipping
what kind of joint is the the glenohumeral joint?

ball and socket
ratio of humerous to glenoid in the glenohumeral joint

4:1 ... leads to increased mobility and decreased stability
movements at glenohumeral joint
- flex/ext
- abd/add
- IR/ER

labrum in the shoulder

fibrocartilage that deepens the glenoid cavity
where is the coracohumeral lig
