It helps carry sensory signals (feeling) and motor signals (movement) between the brain\/spinal cord and specific regions of the neck and shoulder area. Clinicians commonly refer to the C4 nerve root when evaluating neck pain, shoulder-girdle symptoms, and certain patterns of numbness or weakness. It is also discussed when planning imaging, injections, anesthesia-related nerve blocks, or cervical spine surgery."}
