Which fact is incorrect for Pectoralis Major?
Attachments include medial 1/2 of clavicle, anterior sternum, coastal cartilages ribs 1-6, and medial lip of bicipital groove
Innervated by both medial and lateral pectoral nerves
Main action is adduction, horizontal adduction and medial rotation of shoulder
Synergists include latissimus dorsi, subscapularis and teres major
Which action is NOT performed by Coracobrachialis?
Flexion at shoulder
Adduction at shoulder
Horizontal adduction at shoulder
