Pectoralis major


A, O, I

Clavicular head

Clavicular head

O - medial half of the clavicle
I - distal attachment: lateral lip of the bicipital grove (intertubercular groove)of the humerus
A - flexion of the shoulder


Named for size and location

2

Pectoral major


A, O, I

Sternocostal head

O: (proximal/axial attachment)manubrium & body of sternum. 1st to 6 or 7 costal cartilages

I: (distal attachment) lateral lip of the bicipital groove of the humerus


A: extension of the shoulder

Pectoralis major

Actions of both heads - synergysts

- Adduction
- Horizontal adduction
- Medial rotation

4

Types of ribs

True ribs - 7 have their own costal cartilage

False ribs - 3 share costal cartilage

Floating ribs - 2 without attachment to the sternum
