Latissimus Dorsi


O


I


A

O: Spinous processes of T7-L5, Ribs 9 -12 (posterior surface), posterior iliac crest, posterior sacrum


I: Intertubercular groove of humerus (medial lip)


A: Extends the humerus, medially rotates the humerus, adducts the humerus (posteriorly)


Teres Major


O


I


A

O: inferior third of the lateral border of the scapula


I: intertubercular drive of the humerus


A: Extends the humerus, medially rotates the humerus, adducts the humerus

Supraspinatus


O


I


A

O: supraspinatus fossa of the scapula


I: greater tubercle of the humerus


A: abducts the humerus (first 10-15 degrees), prevents downward dislocation of humerus

Infraspinatus


O


I


A

O: infraspinatus fossa of the scapula


I: greater tubercle of the humerus


A: laterally rotates the humerus

Teres minor


O


I


A

O: superior two thirds of the lateral border of the scapula


I: greater tubercle of the humerus


A: laterally rotates the humerus, adducts the humerus

Subscapularis


O


I


A

O: subscapular fossa of the scapula


I: lesser tubercle of the humerus


A: medially rotates the humerus

Deltoid


O


I


A

O: lateral third of the clavicle, acromion process, scapular spine


I: deltoid tuberosity


A: flexes the humerus (anterior fibers), medially rotates the humerus (ant fibers), abducts the humerus (middle fibers), extends the humerus (posterior fibers), laterally rotates the humerus (post fibers)

Pectoralis major


O


I


A

O: medial half of the clavicle, edge of the sternal body, ribs 1-7 (costal cartilage)


I: intertubercular groove of the humerus (lat lip)


A: Adducts the humerus (ant), medially rotates the humerus, flexes the humerus, extends the humerus

Corachobrachialis


O


I


A

O: coracoid process of the scapula


I: medial humeral shaft (middle region)


A: flexes the humerus, adducts the humerus
