19Name the Function!
Olfactory (I)- smell
Optic (II)- sight
Oculomotor (III)- eyelid eyeball movement
Trochlear (IV)- turns eye down/out (sup. obl.)
Trigeminal (V)- chewing, face touch and pain
Abducens (VI)- turns eye laterally (lat. rectus)
Facial (VII)- controls most facial expressions,
tears and saliva, taste (ant. 2/3)
Vestibulocochlear (VIII)- hearing, equilibrium
Glossopharyngeal (IX)- taste (post. 1/3),
senses carotid BP Vagus (X)- senses aortic
BP, slows heart rate, stimulates digestive
organs taste
Hypoglossal (XII)- controls tongue movement
20Cavernous sinus content
- O TOM CAT
- O TOM are lateral wall components, in order from
superior to inferior. - CA are the components within the sinus, from
medial to lateral. CA ends at the level of T from
O TOM. - See diagram.
- Occulomotor nerve (III)
- Trochlear nerve (IV)
- Ophthalmic nerve (V1)
- Maxillary nerve (V2)
- Carotid artery
- Abducent nerve (VI)
- T When written, connects to the T of OTOM

Accessory (XI)- controls trapezius and
sternocleidomastoid
