Scapulohumeral Rhythm
- 1st 30 degrees is from shoulder joint
- after the scapular joins
- 2:1 ratio

- Superior Angle
- Inferior Angle
- Vertebral (medial) border
- Axillary (lateral) border
- Spine
- Coracoid Process
- Acromion Process
- Glenoid Fossa
Where is scapula found at rest?
- between ribs 2-7
