Question 12

symptoms of damage to the posterior spinal artery

Answer 12

minor (rare) diminished vibration sense

Question 13

symptoms of damage to the anterior spinal artery

Answer 13

paralysis and loss of pain and temperature sensation below the level of the occulsion

Question 14

symptoms of damage to the posterior inferior cerebellar artery

Answer 14

vertigo, loss of balance, ipsilateral “cerebellar signs”, loss of facial sensation

Question 15

symptoms of damage to the anterior inferior cerebellar artery

Answer 15

ipsilateral cerebellar signs

Question 16

symptoms of damage to the pontine arteries

Answer 16

can result in paralysis and loss of sensation in the face, body and limbs
can also affect eye movements and cause diplopia

Question 17

symptoms of damage to the superior cerebellar artery

Answer 17

ipsilateral cerebellar signs

Question 18

symptoms of damage to the posterior cerebral artery

Answer 18

most common- complete or partial blindness in the “hemifield” (half of the visual field) contralateral to the affected side
less common- contralateral somatosensory loss; memory deficits, alexia, visual agnosia

Question 19

symptoms of damage to the middle cerebral artery

Answer 19

deficits can include- contralateral paralysis and sensory loss; abnormal voluntary eye movements; apraxia, aphasia, partial blindness

Question 20

symptoms of damage to the anterior choroidal artery

Answer 20

deficits can include- involuntary movements (basal ganglia), paralysis or sensory deficits in head and body (internal capsule)

Question 21

symptoms of damage to the lenticulostriate artery

Answer 21

same as anterior choroidal
deficits can include- involuntary movements (basal ganglia), paralysis or sensory deficits in head and body (internal capsule)

Question 22

symptoms of damage to the anterior cerebral artery

Answer 22

contralateral paralysis and sensory loss in the leg and foot; apraxia

Question 23

cerebellar signs

Answer 23

ataxic gait
postural and balance deficits
intention tremor
dysdiadokokinesia
nystagmus
generalized weakness (less common)
