 ratus magnus and the chest wall. It anastomoses with the internal mammary, 

 intercostal arteries and the long thoracic. It helps to supply the sterno-clav- 

 icnlar joint.

pari of the artery. It has an axis and gives off three branches. (1) humeral 

 or descending branch which passes down bet ween the Pectoralis major and 

 Deltoid with the cephalic vein, supplying both these muscles; it anastomoses 

 with the anterior and posterior circumflex arteries. (2) the acromial branch 

 which supplies the Deltoid muscle and the acromio-clavicular joint, anastom- 

 osing with the anterior and posterior circumflex and suprascapular arteries
