where is the olfactory nerve located?
rests on the cribiform plate of the ethmoid bone.
what is the course of the optic nerve? accompanied by what?
through optic canal of sphenoid bone accompanied by the ophthalmic artery
what are the clinical disorders associated with the optic nerve? what age group are you able to see this in?
blindness and diplopia. I newborns
what is the osteopathic cranial field application for the optic nerve?
optic foramen between two roots of the lesser wings of the sphenoid--> the optic chiasm lies above the SBS and between the layers of the tent
what are the five eye muscles associated with the oculomotor nerve?
superior, inferior, medial rectus; inferior oblique and levator palpebrae superioris
where does the oculomotor nerve run?
over the attached border of the tentorium, through lateral wall of the cavernous sinus and superior orbital fissure.
what are the clinical disorders associated with the oculomotor nerve?
ptosis, diplopia, dilated pupil
what nerve controls the superior oblique muscle?
CN 4--> trochlear
what does the trochlear pierce?
pierces the free border of the tentorium then follows CN III
what are the clinical disorders associated with cranial nerve 4?
diplopia
what nerve controls the lateral rectus?
cranial nerve 6--> abducens
where does the abducens nerve run?
beneath petrosphenoid ligament beside dorsum sellae, in lumen of cavernous sinus, then with CN III
what are the associated clinical disorders with abducens?
diplopia (eye can't abduct). seen in head trauma
what happens to the tentorium cerebelli when the sphenoid has a torsion?
the tentorium is tightened and nerves 3, 4, 5, and 6 are affected because they run under the tentorium as well as deter the venous drainage which can leave to glaucoma (if of the cavernous sinus).
how can strabismus be acquired?
congenital
acquired through CN paralysis
neuromuscular disorders
how is strabismus often compensated by the patient?
through postural changes.
T/F

Strabismus can be effectively addressed through OCF.
true
what muscles are innervated by trigeminal nerve?
muscles of the mastrication + muscles from 1st arch (tensor veli palatine, tensor tympani, mylohyoid, anterior belly of the digestric)
what areas of the body are given sensory through the trigeminal nerve?
face, scalp, structures above tentorium cerebelli
which division of the trigeminal nerve crosses through the superior orbital fissure?
V1
which division of the trigeminal nerve crosses through the Foramen rotundum?
V2 (maxillary)
which division of the trigeminal nerve crosses through the Foramen ovale?
V3 (mandibular)
what is another name for trigeminal neuralgia? what does it feel like?
Tic doloreux
severe stabbing sharp pain along the V2 and/ or V3 divisions of CN V
why to pts get trigeminal neuralgia?
d/t dural restriction over the petrous ridge
what muscles are supplied by the facial nerve?
facial expression, scalp, aurcile, buccinator, platysma, stapedius, stylohyoid, post. belly of digastric
where does the facial nerve provide taste to?
anterior 2/3 of tongue
what glands are innervated by the facial nerve?
submandibular, sublingual, intralingual glands
How does the facial nerve affect hearing?
innervating stapes
what is the course of the facial nerve?
sweeps over abducens nerve→ joins CN VIII in internal acoustic meatus, → facial canal → stylomastoid foramen → posteroaricular foramen→ parotid gland, muscles of facial expression
what is belly's palsy?
complete paralysis of muscles of facial expression
if only the low face is affected via facial nerve, what would it be called?
stroke
if a pregnant women can in with bell's palsy, what could it be d/t?
swelling
how do you know that you are in the right position for txing sinusitis via the sphenopalatine ganglia?
the pt starts tearing.
what is the course of the vestibulochoclear nerve?
through the internal acoustic meatures--> petrous portion of the temporal bone
what is the vestibulochoclear nerve responsible for?
hearing, balance and eye position
what dysfunctions are associated with the vestibulochoclear nerve?
vertigo, loss of hearing, nausea, motion sickness
what is the muscle associated with tennis serving that can affect the temporal bone?
SCM
what is the glossopharyngeal nerve sensory to? what does it supply taste to?
oropharynx; posterior 1/3 of tongue
what is the glossopharyngeal nerve motor to?
stylopharyneus
where does the glossopharyngeal exit the skull? what does it mediate
