O - transverse processes of cervical vertebra
I - ant and Medius to 1st rib, posterior to 2nd rib
A - Accessory to inspiration, hold your head up.
Pectoralis Major
O - clavicle (Clavicular head), sternum and costal cartilages of the 2nd - 6th ribs
I - greater tubercle and intertubercular sulcus of the humerus.
A - Adduction and medial rotation of the humerus
Pectoralis minor
O- Anterior 3,4,5 ribs
I - coracoid process of scapula
A - Elevates ribs if scapula fixed, protracts (adduction as in pushup or punch) scapula
O - 1st rib
I - clavicle
A - stabilises clavicle
External - O - inferior border of ribs 1 - 11
I - superior border of ribs 2 - 12
