UE bones/ligs/muscles Flashcards



flexor digitorum profundus


Pronator quadratus




Flexor carpi ulnaris



Infraspinatus
3A: stabilize, adduction and laterally rotate glenohumeral joint O: infraspinous fossa I: greater tubercle of humerus
Biceps brachii
3A: flex elbow - flex glenohumeral joint - supination O: short head coracoid process - long head supraglenoid tubercle I: tuberosity of the radiu and aponeurosis of biceps brachii


Rotator cuff muscles
All stabilize the humerus Supraspinatus - infraspinatous - trees minor - subscapularus





Flexor pollicis longus


Pronator teres


Dorsal interossei


aconeus



















Supraspinatus
2A: stabilize and abduct glenohumeral joint O: supraspinous fossa I: greater tubercle of humerus



palmaris longus








Brachioradilis








Opponens pollicis

Subsacapularis
2A: medially rotate and stabilize glenohumeral joint O: subscapular fossa I: lesser tubercle of the humerus

Supinator







Tricpes brachii
1/2A: all heads extend elbow - long head extend and addict glenohumeral joint O: long head in infraglenoid tubercle - lateral head posterior surface of proximal half of humerus - medial head posterior surface of distal half of humerus I: olecranon process
Teres major
3A: extend, adduction, and medially rotate glenohumeral joint O: inferior angle and lower 1/3 of lateral border of scapula I: crest of the lesser tubercle of the humerus

Abductor pollicis longus






Brachialis






extensor digitorum

Teres minor
3A: stabilize, laterally rotate and adduction glenohumeral joint O: upper 2/3 of lateral border of scapula I: greater tubercle of the humerus

Flexor digitorum superficialis

Palmar interossei


extensor carpi ulnaris

Deltoid
1/3/3A: all fibers abduct glenohumeral joint - anterior fibers flex, medially rotate, and horizontally adduct glenohumeral joint - posterior fibers extend, laterally rotate, and horizontally abduct glenohumeral joint O: lateral 1/3 of clavicle, acromion, and spine of scapula I: deltoid tuberosity
