22 Mixed CN trigeminal n. facial n. glossopharyngeal n. vagus n.
23 Trigeminal nerve V pons Has three divisions: ophthalmic, maxillary, and mandibular nerve Has both sensory and motor components. It is the main sensory nerve for head and face. Its motor nerve innervates the muscles of mastication, etc.
24 Three divisions: Ophthalmic Superior orbital fissure into orbital cavity Maxillary-foramen rotundum into pteygopalatine Mandibular foramen ovale
25 Trigeminal nerve ophthalmic N
26 Trigeminal nerve ophthalmic N superior orbital fissure Lacrimal nerve to lacrimal gland. Frontal nerve to forehead Nasociliary nerve to eyeball, part of nasal cavity, and skin of dorsum of nose from root to top.

49 SUMMARIZE Nerves of eye Nerves of tongue nerves of pharynx
50 Case A 49-year-old man woke up one morning to find the right side of his face paralyzed. When examined by his local medical practitioner, he was found to have complete paralysis of the entire right side of the face. He was also found to have severe hypertension. The patient talked with slightly slurred speech. The physician told the patient that he had suffered a mild stroke, and he was admitted to the hospital. The patient was later seen by a neurologist who disagreed with the diagnosis.
