Question | Answer |
What are the rotator cuff muscles? | Supraspinatus, infraspinatus, Teres minor, subscapularis |
Supraspinatus - origin | supraspinous fossa |
supraspinatus - action | abduction, some lateral rotation, stabilization |
supraspinatus - innervation | suprascapular |
supraspinatus - insertion | greater tubercule of the humerus |
infraspinatus - origin | infrapsinous fossa |
infraspinatus - insertion | greater tubercle of humerus |
infraspinatus - action | lateral rotation, extension of humerus |
infraspinatus - innervation | suprascapular |
teres minor - origin | upper 2/3 border of scapula |
teres minor - insertion | greater tubercle |
teres minor - action | lateral rotation, horizontal abduction, extension of the humerus |
teres minor - innervation | axillary |
subscapularis - origin | subscapular fossa |
subscapularis - insertion | lesser tubercle of humerus |
subscapularis - action | medial rotation, adduction of humerus |
subscapularis - innervation | upper and lower supscapular |
levator scapula - origin | transverse process of C1 - C4 |
Levator scapula - insertion | vertebral border of scapula - superior angle |
levator scapula - action | elevates scapula, downward rotation |
levator scappula - innervation | dorsal scapular nerve and brances of C3-C4 |
Serratus anterior - origin | ribs 1-8 or 9 |
serratus anterior - insertion | medial border of the scapula |
serratus anterior - action | abduction, protraction, stabilizes |
serratus anterior - innervation | long thoracic |
pectoralis minor - origin | ribs 3-5 near costal cartilage |
pectoralis minor - insertion | coracoid process of scapula |
pectoralis minor - action | stabilizes scapula and downward rotation, depression, proctraction |
pectoralis minor - innervation | medial pectoral nerve |
rhomboid major - origin | T2-T5 |
rhomboid minor - origin | C7-T1 |
rhomboid major and minor - insertion | vertebral border of scapula |
rhomboid major - action | retraction, rotation, fixes scapula to thoracic wall |
rhomboid minor - action | elevation |
rhomboid major and minor - innervation | doral scapular nerve |
upper, middle and lower trap | external occipital protuberance - C7-T12 |
upper trap - insertion | lateral 3rd of acromion process |
middle trap - insertion | spine of scapula |
lower trap - insertion | root of spine of scapula |
upper trap - action | elevation, upward rotation |
middle trap - action | retraction |
lower trap - action | depression, retraction |
upper, middle, and lower trap - innervation | accessory nerve and branches C3, C4 |
