which nerve is the only one capable of regenerating?

olfactory

14

what is the function of the olfactory nerve (CNi)?

conveys special sensory information related to smell

15

name the specialized epithelial tissue inside the nasal cavity that is involved in smell?

olfactory epithelium

16

which type of sensory information does the olfactory nerve carry?

special sensory

17

which type of sensory information does the optic nerve carry?

special sensory

18

where are nerve cell bodies of the optic nerve found found?

retina

19

what is the function of the retina?

transmits impulses to the brain from the retina at the back of the eye.

20

which types of motor impulses does the oculomotor nerve carry?

somatic motor and visceral motor

21

what is the function of the oculomotor nerve (CN iii)

innervates extrinsic eye muscles that enable most movements of the eye and that raise the eyelid.

22

which cranial nerves work together to supply the eye muscles?

- oculomotor (CN iii)
- trochlear (CN iv)
- abducens (CN vi)

where do the cell bodies of the cranial nerves that supply the eye muscles arise from?

midbrain

which type of motor impulses does the trochlear nerve carry?

somatic motor

26

the trochlear nerve innervates a single muscle, what is the name of this muscle?

superior oblique

27

which muscles does the oculomotor nerve innervate?

- superior rectus
- medial rectus
- inferior oblique
- levator palpebrae superioris
