Template talk:Cranial Nerve Table

From Embryology

There are twelve pairs of cranial nerves; they are attached to the brain and are transmitted through foramina in the base of the cranium. The different pairs are named from before backward as follows:

Cranial Nerves 
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 touch, 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, 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)
