Anastomotic connections between the eleventh nerve and the posterior root of the first cervical nerve in humans.

Abstract

✓ A study of connections between C-1, C-2, and the spinal accessory nerve is reported. Four variations are described from anatomical and clinical points of view. Often the only pathway for the sensory fibers of C-1 to reach the spinal cord is through the rootlets of the eleventh cranial nerve.
