The deep cervical branches supply chiefly the deep structures of thelateral and anterior regions of the neck; they give off the phrenic nerveand contribute to form the hypoglossal loop or ansa cervicalis. The cervical plexus is blocked by injecting the anesthetic fluid inthe immediate vicinity of the transverse processes of the cervicalvertebrae, thus realizing the anesthesia of its
