Cranial Nerve # (...) has both motor and sensory components in three regions, the ophthalmic, maxillary, and mandibular branches.
Sensory Function: -Use sharp implement, i.e., broken handle of cotton tip applicator -Have patient close their eyes -Touch sharp implement to Rt. & Lt. ...; Ophthalmic branch -Touch sharp implement to Rt. & Lt. ...; Maxillary branch -Touch sharp implement to Rt. & Lt. ... areas; Mandibular Branch -Use wisp of cotton from the same cotton applicator for light touch to the lateral (sclera) portion of eye. CN # innervates the surface of the eye, while Cranial Nerve # innervates the closure of the eye reflex |

Sensory nerve testing:
... – These afferent nerves detect pain, temperature and crude touch. These nerves enter the spinal cord and then cross the cord in one or two vertebral levels of their entry point terminating in the cerebral hemisphere on the opposite side ... – These nerve detect position (proprioception), vibratory sensation and light touch. These nerve enter the spinal cord and stay on the same side of entry and cross to the opposite side at the level of the brain stem |
