CRANIAL NERVES
# / NAME / ORIGIN(S) / TERMINATION(S) / FUNCTION(S)I / olfactory / olfactory epithelium / olfactory bulb on inferior surface of cerebral frontal lobe / sense of smell only
II / optic / ganglion cell layer of retinal epithelium / thalamus and midbrain / sense of vision only
III / oculomotor / midbrain / levator palpebrae superioris of
upper eyelid
superior rectus of eyeball
inferior rectus of eyeball
medial rectus of eyeball
inferior oblique of eyeball
iris and ciliary muscles of eye / motor: movement of eyeball and eyelid, accommodation of lens of near vision,
constriction of pupil
sensory: proprioception for the muscles innervated
IV / trochlear / midbrain / superior oblique of eyeball / motor: movement of eyeball
sensory: proprioception for muscle innervated
V / trigeminal / pons / muscles of mastication
sensory from skin of face and
anterior ½ of scalp, mucosa
of nose, mouth, throat; teeth,
surface of eye / motor: muscles of mastication
sensory: proprioception for muscles of mastication; touch, pain, and temperature from structures supplied
VI / abducens / pons / lateral rectus of eyeball / motor: movement of eyeball
sensory: proprioception for muscle innervated
# / NAME / ORIGIN(S) / TERMINATION(S) / FUNCTION(S)
VII / facial / pons / muscles of facial expression
lacrimal gland
buccal, submandibular, and
sublingual salivary glands; sensory from taste buds of
anterior 2/3 of tongue / motor: muscles of facial expression; secretion of saliva and tears
sensory: proprioception from muscles of facial expression, taste
VIII / vestibulocochlear
(auditory) / vestibular branch from semicircular
ducts, saccule, and utricle of inner
ear
cochlear branch from spiral organ of
Corti of inner ear / vestibular branch -- pons and
cerbbellum
cochlear branch -- thalamus / vestibular branch -- sense of equilibrium only
cochlear branch -- sense of hearing only
IX / glossopharyngeal / medulla / stylopharyngeus muscle of
throatparotid salivary glands sensory from taste buds of
posterior 1/3 of tongue receptors of carotid sinus
somatic sensory from posterior
1/3 on tongue / motor: stylopharyngeus muscle for swallowing; secretion of saliva; gagging
sensory: proprioception from stylopharyngeus; taste from posterior 1/3 of tongue and
palate; touch, pain, and temperature from tongue; regulation of blood pressure
and respiration
X / vagus / medulla / muscles of airways, lungs, heart,
esophagus, stomach, small
intestine, most of large intes-
tine, gallbladder; glands of GI
tract named
pancreas
liver / motor: smooth muscle contraction and relaxation of areas innervated; secretion of
digestive juices, decreased force of cardiac muscle contraction, tongue
sensory: sensations from visceral organs supplied; proprioception from muscles
supplied; taste from laryngopharynx
XI / accessory / medulla
spinal cord segments C1 - 6 / pharyngeal muscles of
swallowing
spinal portion to sternocleido-
mastoid and trapezius / motor: cranial portion mediates swallowing; spinal mediates head movements
sensory: proprioception for muscles involved
XII / hypoglossal / medulla / extriinsic and intrinsic muscles
of tongue / motor: movement of tongue
sensory: proprioceptions for muscles innervated
