Nerve XI
Accessory
Sense of smell
damage causes impaired sense of smell
olfactory nerve I
provides vision
damage causes blindness in part or all of visual field
optic nerve II
controls muscles that turn the eyeball
controls iris lens and upper eyelid
Damage causes drooping eyelid, dilated pupil, double vision, inability to move eye in certain direction
oculomotor nerve III
eye movement
damage causes double vision and inability to rotate eye inferolaterally
trochlear nerve IV
largest of cranial nerves
most important sensory nerve of the face
forks into three divisions
trigeminal nerve V
provides eye movement (lateral)
damage = cant rotate eye laterally
abducens nerve VI
major motor nerve of facial muscles expression and salivary glands, tears, nasal, and palatine glands.
Sensory: taste on anterior two thirds of tounge
facial nerve VII
branches of facial nerve are
temporal zygomatic buccal mandibular cervical
nerve of hearing and equilibrium
