Superficial Nerves in the Cervico-Brachial Region. This neuralgic field embraces the whole arm, hand, and shoul- der, up to the occipito-cervical neuralgic region on the one hand, as just described, and to the dorsal neu- ralgic region on the other. We said that the four upper cervical nerves were mostly in volved in the last de- scribed region, and as such we have studied them ; but we see here that the lower four of the eight cervical nerves, together with the first dorsal, go to- gether to make up the starting point from the spine for the great brachial plexus; and Fig. 71.
