Inferior cervical artery of Brachial artery arises from the brachial artery at varying levels usually just before it winds round the first rib from its dorsal face.
It is directed downwards and forward and to the deep face of the brachiocephalicus between it and the omotransversarius.
It supplies branches to the posterior cervical lymph glands, brachiocephalicus, omotransversarius, prescapular lymph glands, supraspinatus and sometimes the sternocephalicus.
