---|---|---|---|---|
Nerve Number | Name | Type | Origin | Function |
CN I | Olfactory | sensory | telencephalon | smell placode |
CN II | Optic | sensory | retinal ganglial cells | vision |
CN III | Oculomotor | motor | anterior midbrain | extraocular muscles eye movements and pupil dilation (motor) |
CN IV | Trochlear | motor | dorsal midbrain | extraocular muscles (superior oblique muscle) |
CN V | Trigeminal | motor/sensory | pons | proprioception, mastication |
CN VI | Abducent | motor | extraocular muscles | control eye movements (lateral rectus muscle) |
CN VII | Facial | motor/sensory | pons | facial expression, taste (tongue anterior and central regions) regulate salivary production. |
CN VIII | Acoustic | sensory | vestibular and cochlear nuclei | hearing/balance placode |
CN IX | Glossopharyngeal | motor/sensory | medulla | swallowing and speech, taste (tongue posterior region) |
CN X | Vagus | motor/sensory | medulla | larynx and pharynx muscles (speech and swallowing), regulates heartbeat, sweating, and peristalsis |
CN XI | Accessory | motor | motor neurons | sternocleidomastoid and trapezius muscles |
CN XII | Hypoglossal | motor | motor neurons | tongue muscles (speech, eating and other oral functions) |
