| Question | Answer |
|---|---|
| rotator muscles | subscapularis, teres minor, infra spinatus , supra spinatus |
| rotator muscles | subscapularis, teres minor, infra spinatus , supra spinatus |
| insertion of brachialis | coronoid process of the ulnar tuberosity |
| action- flex arm | brachialis |
| innervation musclocutanous nerve | biceps brachii, brachialis, coracobrachialis |
| insertion greater tubercle of the humerous | teres minor supraspinatus infraspinatus |
| originabove spine of scapula spinous fossa | supraspinatus |
| supraspinatus | action-abduct humerous innervate 30% |
| innervation - suprascapular nerve | supraspinatus subscapularis, supraspinatus , infra spinatus teres major |
| primary flexor | brachialis |
| action-lateral rotation of humerous | infraspinatus, teres minor |
| origin- infra spinous fossa of scapula | infra spinatus |
| teres minor | origin- lateral border of scapula axillary |
| innervation axillary nerve | teres minor |
| subscapularis | origin- anterior scapula of the subscapular fossa |
| insertion-lesser tubercle of the humerous | subscapularis |
| the only rotator that has a different insertion then the others | subscapularis |
| the only rotator that has a different innervation then the others | teres minor |
| action- medial rotation | subscapularis |
| known for frozen shoulder | subscapularis |
| coracobrachialis | origin-coracoid process of scapula |
| insertion-medial aspect of shaft of humerous | coracobrachialis |
| action-adduct flex the humerous | coracobrachialis |
| teres major | origin-inferior angle of the scapula |
| insertion- intertubercular sulcus, medial lip of the bicipital groove | teres major |
| action- extend adduct medial rotation | teres major |
| anconeus | origin- lateral epicondyle of the humerous |
| insertion-olecranon of the ulna | anconeus, triceps brachii |
| anconeus triceps brachii | extend the elbow |
| innervation-radial nerve | anconeus, triceps brachii |
| triceps brachii orgin | long head- infraglenoid tubercle of scapula |
| triceps brachii origin | lateral head- shaft of the humerous |
| shaft of the humerous | origin for lateral head of triceps brachii, brachialis medial head of triceps brachii |
| origin medial head of triceps brachii | shaft of humerous |
| action of triceps brachii | med/lat extend the elbow, longhead extend hyper extend the humerous |
| biceps brachii origin | long head supra glenoid tubercle of the fossa |
| biceps brachii origin | short head coracoid process of the scapula |
| insertion biceps brachii | tuberosity of the radius fascia of the for arm bicipital aponerosis |
| action- biceps brachii | flex shoulder supinate and flex elbow |
| supinator of the forarm | biceps brachii |
