| Olfactory Nerve (cranial nerve I) Function: sensory for smell |
| Optic Nerve (cranial nerve II) Function: sensory for vision |
| Oculomotor Nerve (cranial nerve III) Function: motor for eyeball movement (4 of the 6 extrinsic eye muscles) & upper eyelid movement (sensory for proprioception in extrinsic eye muscles) |
| Trochlear Nerve (cranial nerve IV) Function: motor for eyeball movement (superior oblique muscle) (sensory for proprioception in superior oblique muscle) |
| Trigeminal Nerve (cranial nerve V) Function: sensory for touch, pain & thermal sensation in face; motor for chewing |
| Abducens Nerve (cranial nerve VI) Function: motor for eyeball abduction (lateral rectus muscle) (sensory for proprioception in lateral rectus muscle) |
| Facial Nerve (cranial nerve VII) Function: sensory for taste (anterior 2/3 of tongue); motor for contraction of facial muscles and activity of lacrimal, nasal, palatine & salivary glands |
| Vestibulocochlear Nerve (cranial nerve VIII) Function: sensory for hearing (cochlear nerve) & equilibrium (vestibular nerve) |
| Glossopharyngeal Nerve (cranial nerve IX) Function: sensory for taste (posterior 1/3 of tongue); motor for swallowing (elevation of larynx & pharynx) |
| Vagus Nerve (cranial nerve X) Function: sensory for taste (epiglottis), baroreception & chemoreception in blood vessels, and sensation from thoracic & abdominal organs; motor for regulation of heart rate, breathing, swallowing/speech & digestive system activity |
| Accessory Nerve (cranial nerve XI) Function: motor for head & neck movement and swallowing (sensory for proprioception in sternocleidomastoid & trapezius muscles) |
| Hypoglossal Nerve (cranial nerve XII) Function: motor for speech & swallowing (sensory for proprioception in tongue muscles) |
| Vagus Nerve (cranial nerve X) Function: sensory for taste (epiglottis), baroreception & chemoreception in blood vessels, and sensation from thoracic & abdominal organs; motor for regulation of heart rate, breathing, swallowing/speech & digestive system activity |
