5. A. cirt'Uinflexa humeri anterior (0. T. anterior circumflex artery) (see Fi*?. 449) 

 goes , directly on the anterior surface of the coUum chirurgicnm hunn'ri , covered by all the 

 muscles, first lateralward , then backward. It supplies these muscles, the shouldi'r joint and 

 by means of 1-2 liranclu's fa^. luiiriciae humeri) the superior epiphysis. 



6. A. circumflexa humeri posterior (0. T. posterior circumtiex artery) (see Figs. 44'.), 

 452 and 454) arises at the same level as the preceding artery, sometimes in common with it. 

 passes backward thmugli the space between the huuKn-us , mm. teretes and caput longum 

 m. tricipitis and surrounds the coUura chirurgicum from. behind and lateralward, lying always 

 upon the bone and covered by all the muscles. It supplies these muscles, the shoulder joint 

 and the skin over the ra. deltoideus; it usually gives off two branches (^(3. nuiriciae hiinici-i) 

 to the superior epiphysis of the humerus.
