Cranial Nerves

Olfactory

• cranial nerve I

• smell (olfaction)

Optic

• cranial nerve II

• sight/vision

• only sends information about light

occulomotor

• optic nerve III

• moves eye muscles (occulus)

• moves iris via intraoccular muscle

• innervates cilliary body

  • bends the shape of the lens

  • moved by the intraoccular muscle

• innervates superior eyelid

trochlear

• cranial nerve IV

• innervates superier oblique muscle

• moves eye

trigeminal

• cranial nerve V

• comes out of pons

• sensation of teeth

• sensation of face

• innervates muscles of mastication

abducins

• cranial nerve VI

• abducts eye innervating lateral rectus

facial

• cranial nerve VII

• does not move tongue

• helps with tasting in the anterior 2/3 tongue innervates most facial musles

• expect superior eyelids

• lacrimal gland (tears)

• innervates submandibular and sublingual salivary glands

vestibulocochlear

• cranial nerve VIII

• balance

• hearing

glossopharyngial

• cranial nerve IX

• posterior 1/3 tongue for tasting

• swallowing

vagus

• cranial nerve X

• decreases heart rate (parasympathetic)

• decreases lung rate

• increases digestive rate

spinal accessory

• cranial nerve XI

• sternocledomastoid

• trapezius

hypoglossal

• cranial nerve XII

• moves tongue

hypoglossal

cranial nerve that deals with smell (olfaction)

olfactory

what cranial nerve deals with sight/vision and only sends informaion about light

optic

what cranial nerve deals with moves eye muscles (occulus), moves iris via intraoccular muscle, innervates cilliary body (bends the shape of the lens moved by the intraoccular muscle), and innervates superior eyelid

occulomotor

what cranial nerve innervates superier oblique muscle in order to move the eye

trochlear

what cranial nerve comes out of pons, deals with sensation of teeth, sensation of face, and innervates muscles of mastication

trigeminal

what cranial nerve moves the eye innervating lateral rectus

abducins

what cranial nerve does not move tongue but helps with tasting in the anterior 2/3 tongue, innervates most facial musles except superior eyelids, innervates the lacrimal gland (tears), and innervates submandibular and sublingual salivary glands

facial

what cranial nerve deals with balance and hearing

vestibulocochlear

what cranial nerve deals with posterior 1/3 tongue for tasting (not movement of tongue) and swallowing

glossopharyngial

what cranial nerve decreases heart rate, decreases lung rate, and increases digestive rate

vagus

what cranial nerve innervates sternocledomastoid and trapezius

spinal accessory

what cranial nerve moves the tongue?

hypoglossal
