Supply: Upper limb

thyrocervical trunk

terminal branches are the ascending cervical and inferior thyroid artery

cervicodorsal trunk (transverse cervical artery)

dorsal scapular artery (deep branch of transverse cervical artery)

anastomoses around the scapula

Supply: levator scapulae and rhomboid
