Term Definition
supraspinatus (rotator cuff) glenohumeral abduction and stabilization; Origin (starts at): supraspinous fossa of scapula; Insertion (ends at): greater tubercle of humerus and the shoulder joint capsule
infraspinatus (rotator cuff) glenohumeral external rotation and stabilization; Origin (starts at): infraspinous fossa of scapula; Insertion (ends at): greater tubercle of humerus and the shoulder joint capsule
suprascapular nerve (C5-6) innervates supraspinatus and infraspinatus
teres minor (rotator cuff) external rotation and stabilization; Origin (starts at): lateral border of scapula; Insertion (ends at): greater tubercle of humerus and the shoulder joint capsule
axillary nerve (C5-6) innervates teres minor and deltoid
subscapularis (rotator cuff) internal rotation, adduction, and stabilization; Origin (starts at): subscapular fossa; Insertion (ends at): lesser tubercle of the humerus and the joint capsule
upper and lower subscapular nerves (C5-6) innervates subscapularis (rotator cuff)
deltoid anterior deltoid= shldr flexion and internal rotation; middle deltoid= straight abduction; posterior deltoid= shldr extension, horizontal abduction, and external rotation; Origin (starts at): lateral 1/3 of clavicle, acromion and spine of scapula; Insertion (ends at): deltoid tuberosity of humerus
coracobrachialis flexion and adduction of the humerus; Origin (starts at): coracoid process of scapula; Insertion (ends at): middle 1/3 of medial humerus
musculocutaneous nerve (C5-7) innervates coracobrachialis
pectoralis major both heads: adduction, horizontal adduction, and internal rotation; clavicular head: flexion of humerus (1st 60 deg. of flexion); sternocostal head: 1st 60 deg. of extension, starting at 180 deg. flexion; Origin (starts at): clavicular head: medial 1/3 of clavicle; sternocostal head: sternum and ribs 1-6; Insertion (ends at): lateral lip of bicipital groove of humerus
clavicular head: lateral pectoral nerve (C5-6); sternocostal head: medial pectoral nerve (C7-T1) innervates pectoralis major
latissimus dorsi shoulder extension, adduction, internal rotation, and shoulder girdle depression; Origin (starts at): T7-12 spinous processes, thoracolumbar fascia, iliac crest and inferior 3-4 ribs; Insertion (ends at): floor of bicipital groove of humerus
thoracodorsal nerve (C6-8) innervates latissimus dorsi
teres major extension, adduction, and internal rotation; Origin (starts at): inferior angle of scapula; Insertion (ends at): medial lip of bicipital groove of humerus
lower subscapular nerve (C6-7) innervates teres major
