The medial branches of the plexus also comprise muscular and communi- cating branches. The first cervical nerve assists in the formation of this series of nerves, forming a slender loop with part of the second nerve in front of the trans- verse process of the atlas. Communicating Branches. â (a) With the sympathetic.âGray rami communi- cantes pass to each of the first four cervical nerves, near their origins, from the superior cervical ganglion or from the trunk below the ganglion, (b) With the vagus nerve.âThe ganglion nodosum of the vagus nerve may be connected by a slender nerve with the loop between the first two cervical nerves. This communica- tion is not constant, (c) With the hypoglossal.âAn important communication occurs between the hypoglossal nerve and the loop between the first and second.
