Ascending branch of transverse cervical artery

The superficial branch of transverse cervical artery ascends beneath the anterior margin of the trapezius, distributing branches to it, and to the neighboring muscles and lymph glands in the neck, and anastomosing with the superficial branch of the descending branch of the occipital artery. 

It has an ascending branch and a descending branch. The descending branch of the transverse cervical artery anastomoses with the deep and dorsal scapular artery which in turn links to the subscapular. This anastomosis is a ring circulation around the scapula where it continues to the suprascapular artery via the circumflex scapular artery.
