WebbThe nerves that convey both are often related to each other. The trigeminal and facial nerves both concern the face; one concerns the sensations and the other concerns the muscle movements. The facial and glossopharyngeal nerves are both responsible for conveying gustatory, or taste, sensations as well as controlling salivary glands. WebbAfferent fibers, arising from the trigeminal nerve and the upper cervical spinal cord segments, innervate the proximal parts of the large cerebral vessels and dura mater. These sensory fibers terminate within the lower brainstem and upper cervical cord. Nociceptive information is then relayed to the thalamus and cortical pain areas.
