10. Cranial Nerve 1: Olfactory Nerve

11. Cranial Nerve II: Optic Nerve

12. Cranial Nerves III, IV, VI: Oculomotor, Trochlear, Abducens
Innervates 4 extraocular muscles and functions in most eye movements
Contains parasympathetic which innervates pupillary constrictor muscles
Trochlear
Nerve exits dorsal surface and crosses over
Moves eye medially and downward
Abducens
Moves eye laterally

15. Cranial Nerve V: Trigeminal Nerve
Trigeminal ganglion
Ophthalmic, maxillary and mandibular divisions
Sensory: Touch, pain, temp, proprioception for face, oral and nasal cavities.
Motor: Muscles for mastication.

16. Cranial Nerve V: Trigeminal Nerve
V1. Ophthalmic
Exits with eye muscle group (superior orbital fissure, through orbit to superior orbital notch/foramina)
Sensory to forehead, nasal cavity
V2. Maxillary
Exits foramen rotundum through wall of maxillary sinus to inferior orbital foramina)
Sensory to cheek, upper lip, teeth, nasal cavity
V3. Mandibular
Exits foramen ovale to mandibular foramen to mental foramen
Motor to jaw muscles-Masseter, temporalis, pterygoids, digastric
Sensory to chin
Taste Sensory to tongue (from facial N.) 16

17. Cranial Nerve VII: Facial Nerve
Motor function: muscles of facial expression.
Parasympathetic function: innervation to lacrimal glands and some salivary gland.
Visceral sensory function: taste from anterior 2/3 of tongue

18. Cranial Nerve VII: Facial Nerve15

19. Cranial Nerve VIII: Vestibulocochlear Nerve
Auditory and vestibular sensation
Travels with facial nerve
Branches go to cochlea, vestibule

20. Vestibular and Cochlear Sensory Organs

21. Cranial Nerve IX: Glossopharyngeal Nerve
Motor function: stylopharyngeus muscle which elevates pharynx during
talking and swallowing.
Parasympathetic function: innervation of parotid salivary gland.

22. Cranial Nerve X: Vagus Nerve
Motor function: pharyngeal muscles & laryngeal muscles
Parasympathetic function: heart, lungs, most if digestive tract.
Somatic sensation function: sensation from pharynx, meninges, external auditory meatus

23. Cranial Nerve XI: Spinal Accessory Nerve

24. Cranial Nerve XII: Hypoglossal Nerve10
