COURSE/DISTRIBUTION: Begins at the third part of the axillary artery under cover of the deltoid. It passes directly around the surgical neck of humerus and anastomosis with the posterior circumflex vessels underneath the deltoid

 

BRANCHES: Muscular and cutaneous branches, which accompany the upper lateral cutaneous nerve of arm to pierce the deltoid in order to supply the skin below the deltoid.
