Document Summary

Muscles that stabilize the scapula: trapezius, o: occipital bone, i: scapula, a, upper fibers = elevation, middle fibers = retraction. Glenohumeral joint (shoulder): deltoid, o: clavicle - anterior fibers. Scapular spine - posterior fibers: i: deltoid tuberosity, a, middle = abduction. Posterior - extension: pectoralis major, o: sternum, clavicle, ribs, greater tubercle of humerus, a: Internal rotation: latissimus dorsi, o: lower spine, iliac crest, i: greater tubercle of humerus, a, teres major. Internal rotation: o: inferior border of scapula, i: lesser tubercle of humerus, a: Extension internal rotation: rotator cuff, supraspinatus, o: supraspinous fossa. A: shoulder abduction: infraspinatus, o: infraspinous fossa. A: external rotation: teres minor, o: lateral border of scapula. A: external rotation: subscapularis, o: subscapular fossa. Long head: superior margin of glenoid cavity. Short head: coracoid process of scapula, i: radial tuberosity, a: elbow flexion, triceps brachii, o:
