Origins and Insertion of shoulder girdle Flashcards
O and I of deltoid
O = Scapula spine, acromion, lateral third of clavicle
I =deltoid tuberosity on lateral side of humerus
O and I of serratus anterior
O = Upper 8-9 ribs I = medial border of scapula
O and I of biceps
O = supraglenoid tubercle of scapula I = radial tuberosity
O and I of coracobrachialis
O = coracoid process I = medial surface border in humerus
O and I of pectoralis major
O = sternum, clavicle I = crest of greater tubercle of humerus
O and I of pectoralis minor
O = ribs 3-5 I = coracoid process
O and I of latissimus dorsi
O = thoracolumbar fascia, spinous process of T07 -T12, L1- L5, post. Third of iliac crest I = intertubercular groove of humerus
O and I of teres major
O = inferior angle of scapula
I – intertubercular groove of humerus
O and I of triceps
O = posterior surface of body of humerus I = olecranon of ulna
O and I of trapezius
O = occipital bone, ligamentum nuchae, spinous process T1 – T12 I = scapula spine, lateral third of clavicle
O and I of teres minor
O = Lateral border of scapula I = greater tuberosity of humerus
O and I of infraspinatus
O = infraspinatus fossa in post. Aspect of scapula I = greater tubercle of humerus
O and I of subscapularis
O = Subscapular fossa I = lesser tubercle of fossa
O and I of levator scapulae
O = transverse process of C1-4 I = superior medial border of scapula
O and I of rhomboid minor
O = spinous process of C7 – T1
I =Medial border of scapula
O and I of rhomboid major
O = spinous process T2-5 I = Medial border of scapula
