Brain bloody supply/ strokes/ lesions

Question 1

ACA

Answer 1

anteromedial surface

-motor and sensory corticies for lower limb –> contralat paralysis and sensory loss OF LOWER LIMB

Question 2

MCA

Answer 2

lateral surface

• temporal lobe –> wernicke
• frontal lobe –> broca
• contralat paralysis/ sensory loss for UPPER LIMB/FACE

Question 3

PCA

Answer 3

posterior, inferior surfaces

-occipital/ visual cortex –> contralat HEMIANOPIA with macular sparing

Question 4

PICA

Answer 4

-lateral medulla
wallenberg syndrome –> nucleus ambiguus effects

contralat loss of pain and temp, ipsi 5,8,9,10,11, horners
-DYSPHAGIA, HOARSNESS

Question 5

AICA

Answer 5

• lateral pons
• lateral pontine syndrome –> paralysis offace, lacrimation, salivation, taste on anterior 2/3 of tongue
• IPSI pain and temp of face, CONTRA pain and face of body

“facial droop means AICA’s pooped”

Question 6

lenticulostriate

Answer 6

striatum, internal capsule

• secondary to poorly controlled HTN
• lacunar infarcts
• contralateral body/ face sensory

Question 7

kluver bucy syndrome

Answer 7

AMYGDALA
assoc with HSV encephalopathy
hyperphagia, hypersexuality, hyperorality

Question 8

frontal lobe

Answer 8

disinhibitio and deficits

primitive relfexes

Question 9

domninat parietal cortex

Answer 9

gerstmann syndrome (angular gyrus)

**non dominant involves hemineglect

Question 10

cerebellar vermis vs hemi?

Answer 10

vermins= truncal ataxia

hemi- intention termor, limb ataxia

Question 11

hippocampus

Answer 11

anterograde amnesia (can’t do NEW memories)
