Vosko I Flashcards
Channels in axon hillock
Cl channels
mesencephalon
midbrain
prosencephalon
forebrain
proseencephalon becomes what
telencephalon and diencephalon
diencephalon becomes what
thalamus
hypothatlamus and retin
telecephalon becomes what
cerebral Cx and basal ganglia
rhombencephalon becomes
metencephalon and myelencephalon
metecephalon becomes
cerebellum and pons
myelencephalon becomes
medulla
CN derived from what parts of brain
1:1:2:2:6 I telencephalon II diencephalon III IV mesencephalon V VI metencephalon VII VIII IX X XI XII myelencephalon
4 major sulci of brain
central- sulcus rolando lateral sulcus- sylvian fissure parietoociipital sulcus cingulate sulcus preoccipital notch
cingulate sulcus
around corpus callosum
gyri in frontal lobe
superior middle and inferior precentral gyrus orbital part triangular part and opercular part part of paracentral lobule orbital gyri, olfactory bulub
brocas aphasia locaiton
opercular part of frontal lobe
brocken speech
lobes in pareital
post central gyrus supramarginal gyrus angular gyrus posterior paracentral lobule precuneus
R side parietal lesions
hemineglect
L side does not exist
where in the world we are?
pareietal lobe
lobes temporal lobe
superior middle inferior
limbic gyrus
fusiform gyrus
wernickes aphasia location
superior temporal lobe
fluent aphasia
lobes in occipital lobe
lateral occipital gyri lingual hyrus cuneus calcarine sulcus fusiform gyrus
lingual gyrus visual field
superior
cuneus visual field
inferior
limbic lobe
isthmus, collateral sulcus, parahippocampal gyrus, rhinal sulcus, uncus, subcallosal area, paraterminal gyrus
cingulate sulcus and gyrus
fear aggression
amygdala
center of telencephalon
basal ganglia
thalamus
internal capsule
role basal ganglia
smooth out movements
separates the thalamic nuclei
internal medullary lamina
3 divisions nuclei in thalamus
anterior
medial
lateral (dorsal/ventral)
what shuts down input of sensory like whne sleeping
thalamic reticular system
patterns for hypothalamic control
anterior (PAN) posterior (SAN) neuroendocrine bi-directional circuitry controls reticulospinal system
rostral hypothalamic lesion vs caudal
rostral never sleep
caudal never wake up
where are the inferior and superior colliculi
midbrain
superior-vision/eye control
inferior- hearing
crus cerebri
cerebral pedunceles
pain modulation
periaqueductal grey
lesion in inferior colliculi
inability to localize sound because auditory pathway bilateral
VTA
ventral tegmental area
release dopamine to nucleus accumbens
“i want or I need”
pons parts
tegmentum and basal pons
what is in pons
locus ceruleus
micturition center
CN nuclei
reticular formation
locus ceruleus
secrete Epi and Norepi
cerebellum
proprioception input
coordinates complex movements
roles of medulla
resp center cardiac center consciousness center pathway for all ascneding descending information CN nuclei
DCML
sensory two point discrimination
vibration
proprioception
where are cell bodies for DCML
DRG
where DCML enter spinal cord
dorsal faniculus and ascends to medulla
decussation DCML
in medulla- internal arcuate fasiculus
runs up in medial lemniscus here on up
secondary neurons of DCML synapse where
thalamus VPL
than goes to primary sensory Cx
types of DCML
cuneatus more lateral: limbs
and gracilus: more medial, trunk
Anterolateral system
sensory
pain
temp
crude tough
cell bodies ALS
dorsal route
where does ALS pathway enter
lisour fasciculus ascends then synapses in dorsal horn
decussation ALS
anterior white commisure
tract ALS runs in
antero lateral spinothalamic pathway to VPL thalamus
ion channels on pacinian corpuscles
TRP channels
4 spinocerebellar tracts
unconscious proprioception
fine: cuneocerebellar upper half body
rostralspinocerebellar (don’t need to know)
dorsal(fine movement) and ventral (gross) spinocerebellar tracts
ventral spinocerebellar tract decussation
decussates twice so is ipsilateral
ventral trigeminothalamic tracts
nociceptive info of head
