Cranial Nerves Flashcards
pairs of nerves
12 pairs
nerve function that is based on sensing or detecting the stimuli
sensory/afferent
nerve function that is based on movents and creates effects
motor/efferent
where the brain is floating on CSF
cranial vault
where the brain is on top of

motor
nerve that conveys information on smell
olfactory nerve
where the olfactory originates from
frontal lobe
nerve that forms the optic chiasm
optic nerve
where the optic originates from
occipital lobe
where the oculomotor originates from
midbrain
where the trochlear originates from
midbrain, inferior colliculus
nerve that is responsible for EOM
oculomotor nerve
meaning of EOM
extra ocular muscles
EOM
superior rectus inferior rectus medial rectus lateral rectus superior oblique inferior oblique
muscles that do not connect w EOM
superior oblique
lateral rectus
nerve that supplies superior oblique
trochlear nerve
where the trigeminal originates from
mid-pointe level
nerve that has 3 branches: opthalmic maxillary and mindibular
trigeminal nerve
trigeminal responsible for forehead
opthalmic
trigeminal responsible for cheeks
maxillary
trigeminal that is responsible for jaw
mandibular
where the abducen originates from
dorsal lower portion of the pons
nerve that supplies the lateral rectus
abducen nerve
where the facial originates from
pons
nerve that has 2 branches: lacrimal and salivary
facial nerve
facial nerve that is responsible for tears & other name
lacrimal, greater superficial petrosal nerve
facial nerve that releases saliva & other name
salivary gland, chorda tympani
nerve that is responsible for hearing sensation & other name
vestubule-cochlear, acoustic
receptor organ inside cochlea
otolith
glossopharyngeal motor fibre originates from?
rostral nucleus ambiguus
what does the motor fibres in glossopharyngeal nerve supply?
stylopharyngeus muscle
glossopharyngeal sensory fibre originate from?
tractus solitarius
glossopharyngeal fuction that is responsible for the taste and sensation for the posterior tongue and pharynx
sensory
where does the parasympathetic fibres of the glossopharyngeal nerve originate from?
inferior salivatory nucleus
glossopharyngeal function that is responsible to provide an input to the patrotid gland
parasympathetic
where the vagus nerve originates from
dorsal motor nucleus of vagus
nucleus ambiguus
nerve that controls soft palate, pharynx and larynx
vagus nerve
convey taste from epiglotis and sensation from pinna
vagus nerve
where the spinal accessory originate from
nucleus ambiguus in the medulla
accessory nucleus in the upper cervical spinal cord
nerve that supplies the sternocleidmastoid and trapezius muscle
spinal accessory nerve
where the hypoglossal originate from
hypoglossal nucleus in the posterior part of the medulla
nerve that innervates the tongue
hypoglossal nerve
Nerves that go out of the cranium
