subscapularis - 2Supraspinatus innervationSuprascapular nerve C4,C5,C6
- 3Supraspinatus originSupraspinous fossa of scapula
- 4Supraspinatus insertionsuperior facet of greater tubercle of humerus
- 5Supraspinatus actionworks with deltoid to abduct the humerus
stabilizes the shoulder joint by snubbing - 6supraspinatus blood supplySuprascapular artery
- 7Infraspinatus innervationSuprascapular nerve C5,C6
- 8Infraspinatus originInfraspinous fossa of scapula
- 9Infraspinatus insertionMiddle facet of greater tubercle of humerus
- 10Infraspinatus actionlaterally rotates humerus, helps hold humeral head in place by snubbing
- 11infraspinatus blood supplysuprascapular artery
- 12Teres minor innervationAxillary nerve
- 13Teres minor originMiddl part of lateral border of scapula
- 14teres minor insertioninferior facet of the greater tubercle of humerus
- 15Teres minor actionlaterally rotates humerus
snubbs - 16Subscapularis innervationUpper and lower subscapular nerves C5,C6,C7
- 17Subscapularis insertionlesser tubercle of humerus
- 18Subscapularis actionMedially rotates and adducts humerus
snubbs - 19Costoclavicular ligament axis forelevation and depression and for protraction and retraction
main check for elevation - 20Coracoclavicular ligament does whatProvides joint stability and is stronger than the clavicle itself
Lateral portion of the coracoclavicular ligament is the Trapezoid ligament
The medial portion of the conoid ligament - 21Scapulohumeral rhythmRefers to relatively uninterrupted movement of upper extremity from dependent position to full abduction
- 22Scapulohumeral rhythm full abduction180 Degrees
- 23Scapulohumeral rhythm ROM by glenohumeral joint120 degrees
- 24Scapulohumeral rhythm ROM by scapulothoracic movement60 degrees total
40 degrees by sternoclavicular
20 degrees by acromioclavicular - 25Steps in arm abduction movement of scapula (# and muscles)1
serratus anterior clamps scapula to thoracic wall - 26Steps in arm abduction snubbing of head of humerus (# and muscles)2
rotator cuff muscles - 27Steps in arm abduction First few degrees of abduction (# and muscles)3
supraspinatus - 28Steps in arm abduction External rotation of humerus (# and muscles)4
infraspinatus - 29Elevation of scapula muscleslevator scapulae and rhomboids
- 30Depression of scapula musclesLatissimus dorsi
- 31Extension of shoulder musclesPosterior deltoid and latissimus dorsi mainly
Teres major and minor, infraspinatus, sternal head of pec major, triceps longus assist - 32Flexion of shoulder musclesanterior deltoid mainly
pec major, coracobrachialis, and biceps brachii assist - 33Abduction of scapula musclesserratus anterior
- 34Abduction of shoulder musclesmiddle deltoid assisted by biceps brachii
- 35Adduction of scapula musclesmiddle trap
- 36Adduction of shoulder musclesmiddle pec major and latissimus dorsi
assisted by teres major, anterior deltoid, coracobrachialis and long triceps - 37Rotation of scapula musclesrhomboids and levator scapulae
- 38Rotation of scapula musclesserratus anterior and force couple of upper and lower trap
- 39Deltoid paralysis d/taxillary nerve
- 40serratus anterior paralysis d/tlong thoracic nerve
- 41most common tear in rotator cuffsupraspinatus
