The circumflex scapular is a large branch off of the subscapular artery. The circumflex scapular winds around the axillary border of the scapula between the subscapularis and teres minor. It passes through the triangular subdivision of that general triangular space which is situated at the axillary border of the scapula, to the dorsum of this bone. Here, it anastomoses with the suprascapular and deep scapular branch of the transverse cervical arteries. The space through which it passes is bounded by the subscapularis, the teres minor, the teres major, and the long head of the triceps. A small branch is given off from the circumflex scapular which enters the subscapular fossa beneath the subscapular muscle.
