Cranial Nerve I |
Olfactory (sensory) is within the olfactory mucosa and projects to olfactory bulb |
|
|
Cranial Nerve II |
Optic (sensory) Rec's visual input from eye on ganglion cells in retina and projects to lateral geniculate, superior colliculus |
|
|
Cranial Nerve III |
Oculomotor for medial/superior/inferior rectus and inferior oblique. (eye mvmt, pupillary contraction) carries parasympathetic fibers. Lies within brainstem oculomotor nucleus. receives input from PPRF |
|
|
Cranial Nerve IV |
Trochlear- superior oblique mvmt (eye mvmt, pupillary contraction). Lies within brainstem's trochlear nucleus, receives input from PPRF (paramedial pontine reticular formation). this is the only crossed cranial nerve. |
|
|

|
|
Cranial Nerve VI |
Abducens (eye mvmt, pupillary contraction) lateral rectus muscle from within the abducens nucleus of brain stem; rec's inpur from PPRF. |
|
|
Cranial Nerve VII |
Facial (sensory & motor) carries parasympathetic fibers. Facial expression, platysma, stapedius. sits within facial nucleus of brain stem. |
|
|
Cranial Nerve VIII |
Vestibulocochlear (special senses) auditory and vestibular input from inner ear. within cochlear and vestibular ganglions. |
|
|
Cranial Nerve IX |
Glossopharyngeal (sensory & motor) carries parasympathetic fibers. general sensation & taste from posterior 1/3 tongue, soft palate & auditory canal. Sensory info from carotid body & sinus. Projects to solitary tract & nucleus. |
|
|
Cranial Nerve X |
Vagus (sensory & motor) carries parasympathetic fibers. Stylopharyngeus muscle and soft palate. Autonomic control of thoracic and abdominal viscera. |
