Brain-Simplified Flashcards
respiratory and cardiac centers
autonomics
CN 5-12
medulla and pons
reflexes to light and sound
proximal flexor relay
motoric relay
CN 3and 4
midbrain
relay station
sensory fibers
thalamus
integration of sensory infomraiton
pulvinar
ventral posteromedial
sensory from face
ventral posterolateral
sensory from arms and legs
lateral geniculate
sensory from eyes
medial geniculate
sensory from ears
intellect and association
cerebrum
localization “somesthetic cortex”
Brodman 1, 2, 3,
problem solving
parietal lobe
vision
brodman 17
occipital lobe
superior lobe of temporal
hearing
inferior lobe of temporal
long term memory, smell
hippocampal cells
memory
damage to hippocampus
anterograde amnesia
parahippocampal cells in uncal area
smell
what is wernicke’s area
junction of parietal occipital and temporal lobe
sensory matching, interpretation
what destroys wernicke’s area
B1/thiamine deficiency due to alcoholism
what happens with wernicke-korsakoff syndrome
develop sensory aphasia:can’t understand language
word blindness in angular gyrus: can read, see, but not understand
voluntary motor
frontal lobe
precentral gyrus
brodman 4,4s,6
corticospinal tracts
what are the corticobulbar tracts aka
pyramadal tracts
where does corticobulbar start
giant cells of betz
executive function
personality
motor aphasia
broca’s speech area in inferior frontal lobe on left
broadens area 44
what supplies the motor aphasia
middle cerebral artery
limbic system
associated with amygdala
pleasure or pain
do i need to remember for survival
basal ganglia
inhibits thalamus (stop motor response) provide background muscle tone
what happens when he basal ganglia dysfunctions
trivial information elicits motor response
Parkinsons disease
what is parkinson akak
paralysis agitans
describe parkinsons
exhibits pill rolling tremor mask-like face forward stoop posture shuffling/propulsive gait lead pipe AKA cogwheel rigidity
what are inclusion bodies
levy bodies
from decrease dopamine from substantial nigra in midbrain
what does the caudate of the basal ganglia do
secreates GABA
what does a genetic defect in caudate casue
huntingtons chorea
males
fatal by 50
what does the striatum of the basal ganglia do
putamen + caudate
internal capsule separates caudate and putamen
what does the lentiform of the basal ganglia do
globus pallidus + putamen
hunger thirst temperature regulation sex rage fear
hypothalamus
balance
equilibrium
involuntary coordination
unconscious proprioception
cerebellum
