what does cranial nerve (I), what is it called, what does it exit from, and what is it used for
olfactory nerve (I)
used for smell
exits through the cranial cavity through the cribriform plate
what does cranial nerve (II), what is it called, what does it exit from, and what is it used for
optic nerve (II)
not a true extension of brain
exits through cranial cavity through optic canal
used for vision
what does cranial nerve (III), what is it called, what does it exit from, and what is it used for
oculomotor (III)
exits through cranial cavity through superior orbital fissure
motor to most extra-ocular muscles (move eyeball)
PARASYMPATHETIC (pupillary constriction, accomodation of lens)
what does cranial nerve (IV), what is it called, what does it exit from, and what is it used for
trochlear (IV)
exits through cranial cavity through superior orbital fissure
motor to one extra-ocular muscle
what does cranial nerve (V), what is it called, what does it exit from, and what is it used for
trigeminal (V)
has 3 divisions:
V1, V2, V3
sensory from most of head, including all teeth
motor to muscles of mastication
what are the divisions of the trigeminal nerve, and where do they exit from
V1 opthalmic: exits cranial nerve cavity through superior orbital fissure
V2 maxillary: exits cranial cavity through foramen rotundum
V3 mandibular: exits cranial cavity through foramen ovale
what does cranial nerve (VI), what is it called, what does it exit from, and what is it used for
abducent (VI)
exits cranial cavity through superior orbital fissure
motor to one extra-ocular muscle
what does cranial nerve (VII), what is it called, what does it exit from, and what is it used for
exits cranial cavity through internal auditory meatus and stylomastoid foramen
motor to muscles of facial expression
taste from anterior 2/3 of tongue
PARASYMPATHETIC (lacrimal gland, submandibular and sublingual salivary gland)
what does cranial nerve (VII), what is it called, what does it exit from, and what is it used for
exits cranial cavity through internal auditory meatus and stylomastoid foramen
motor to muscles of facial expression
taste from anterior 2/3 of tongue
PARASYMPATHETIC (lacrimal gland, submandibular and sublingual salivary gland)
what does cranial nerve (VII), what is it called, what does it exit from, and what is it used for
exits cranial cavity through internal auditory meatus and stylomastoid foramen
motor to muscles of facial expression
taste from anterior 2/3 of tongue
PARASYMPATHETIC (lacrimal gland, submandibular and sublingual salivary gland)
what does cranial nerve (VIII), what is it called, what does it exit from, and what is it used for
vestibulocochlear (VIII)
exits cranial cavity through internal auditory meatus
hearing and balance
what does cranial nerve (IX), what is it called, what does it exit from, and what is it used for
glossopharyngeal (IX)
exits cranial cavity through jugular foramen
motor to soft palate
visceral sensory from most cervical, thoracis and abdominal viscera
PARASYMPATHETIC (most cervical, thoracic and abdominal viscera)
what does cranial nerve (XI), what is it called, what does it exit from, and what is it used for
accessory (XI)
unusual, in that it arrives from C1-C5, rather than brain
exits through jugular foramen
motor to sternocleidomastoid and trapezius muscle
what does cranial nerve (XII), what is it called, what does it exit from, and what is it used for
hypoglossal (XII)
exits cranial cavity through hypoglossal canal
motor to intrinsic and most extrinsic muscles of tongue
where do muscles of the face originate from
from superficial fascia, originate from bone or fascia and insert into the skin of the face.
all are innervated by the facial nerve (CN VII)
describe the route the V1 nerve takes
exits the skull through the superior orbital fissure and enters the orbit
one of its branches exits through the supra-orbital foramen as the supra-orbital nerve, to innervate the upper eyelid, forehead and scalp
describe the route the V2 nerve takes
maxillary
exits the skull through the foramen rotundum and enters the inferior orbital fissure
continues forward in the infra-orbital canal and exits through the infra-orbital foramen as the infra-orbital nerve to innervate the:
lower eyelid, cheek, side of the nose and upper lip
describe the route the V3 nerve has to take
mandibular
exits the skull through foramen ovale
it branches include the inferior alveolar branch which enters the mandibular foramen, travels through bone within the mandibular canal and exits through the mental foramen as the mental nerve to innervate the lower lip and the chin, and the auriculotemporal nerve to innervate the temple
how many gangion are there, what are their names
ciliary gangion
pterygopalatine
submandibular
otic
glands above the oral fissure are innervated by what parasympathetics
by parasympathetics on V1 and V2
how many facial nerves are there, how many ganglion are there
3 facial nerves
4 ganglion
what does the ciliary ganglion serve
CN VIII
fibers that target muscles of pupil and lens
what does the pterygopalatine ganglion serve
serves cranial nerve VII
lacrimal
glands below the oral fissure are innervated by
parasympathetics on V3
what does the otic ganglion serve, and what does it go through
serves CN IX
goes through foramen ovale
and works on the parotid gland
