m: brainstem / CN5 Flashcards
parts of brainstem
midbrain pons medulla
where is cerebellum attached
posterior surface of brainstem
is cerebellum in front of behind 4th ventral
behind
what ascending tracts are in brainstem
anterolateral systems
PCML
spinocerebllar
which descending tracts are in brainstem
corticospinal tract
corticobulbar tract
where do cerebellar connections come from
pontine nuclei
whats intrinsic system in brainstem
reticular formation
neurotransmitter system
central pattern generators
where are cranial nerve nuclei
brainstem
responsible for voluntert motor activity
corticospinal tract
where is corticospinal tract
under cerebral peduncles, bons and pyramids
where do corticopsinal fibres midline
caudal medulla (pyramid decssuation)
major feature of posterior surface midbrain
inferior superior colliculi
inferior colliculi
auditory pathway
superior colliculi
visual reflexes
cerebellar peduncles
in pons connect brainstem and cerebellum
name the 3 cerebellar peduncles
inferior middle superior
key features of caudal medulla
fas grace and cute
what separates fas grace and cute
posterior median sulcus
Posterior column carry what
senior info (proprio, fine touch, disrcrminatve touch, vibration)
where is 4th ventricle
over rostal medulla /pns
where does the 4th ventricle open up
obey
where does trigmenal nerve emerge from
mid pons
where does trigemal sensory ganglion sit
floor or middle cranial fossa
three branches of trigeminal
ophthalmic
maxillary
mandibular
where does ophthalmic bench exit through
superior orbital fissure
where does maxillary branch exit through
foramen rotunda
where does mandibular exit through
foramen oval
main sensory nerve of head
trigmenal
whats sense does trigeminal carry
pain, temp
disc touch
vibration
proprio
do all divisons of trigmeanl Carry the same
yes
what does mandibular division do thats special
motor mm mastication
what does trigemal carry
afferent sensory (GSA)
efferent motor
(SVE)
whats GSA for trigeminal
general sensation from head and neck
whats SVE for tigmenal
mm for mastication
wheres trigmenal tract on caudal medulla
top corners
where tract extend to
medulla to pons
wheres tri nucleus
under top right corners
chief nucleus trigmenal where
mid pons
whats nucleus on trigmenal do
touch vibration
theres motor nuclus of trigmeanl
mid pons
wheres mesencephalic nucleus of trigeminal
caudal midbrain
whats mesencephalic do
proprioception from mm of mastication
whats on the inside nuclues or tract
nucleus
top down wheres uncle of chief mesencephalic and motor
cheif, mesencepahic
motor
