The suprascapular artery runs laterally and downwards, under cover of the sternomastoid, across the scalenus anterior and the phrenic nerve, and then laterally behind the intermediate third of the clavicle, in front of the subclavian artery, towards the posterior angle of the triangle. There, it joins the suprascapular nerve and decends to the scapula. Behind the clavicle, it is closely accompanied by one or two veins. The main suprascapular and transverse cervical veins end in the external jugular vein.
