- main blood supply to humeral head arises from anterolateral branch of anterior humeral circumflex artery;
- this vessel passes laterally to long head of biceps & forms arcuate artery;
- arcuate artery:

Anatomy:
- coracoid process can be palpated thru anterior deltoid muscle one to two finger breadths below outer portion of clavicle;
- one finger breadth lateral to coracoid is the GHJ;
- provides a palpable guide to deltopectoral groove;

- Infraspinatus: primary external rotator of humerus;
- Posterior Deltoid
- Teres Minor
Discussion:
- the posterior rotator cuff is important for maintenance of necessary force couples in axial (transverse) and coronal planes.
...

Anatomy:
- GHJ has a greater ROM than any other joint;
- Bony Anatomy:
- it's shallow, & is more akin to a grapefruit in saucer than ball in socket.

major internal rotators are teres major, , latissimus, pect major;
- latissimus dorsi & teres major insert along medial lip of bicipital groove & pectoralis major along lateral lip and also serve as internal rotators;
- these muscles comprise larger mass than those...
