vertebral artery
D
Posterior Spinal a.
Anterior spinal a.
provides - ventral 2/3 of spinal cord
medial medulla
branch in spinal cord -
- paralysis
- loss of pain and temp below stroke
branch in medulla
- contralateral sesnory loss and paresis
- ipsilateral tongue paralysis

what does this supply?
what are some sx?
PICA
supplies:
- cerebellum
- cerbellar cortex
- dorsolateral medulla and pons
sx: Wallenburg’s syndrome: vertigo, loss of balance, ipsilateral “cerebellar signs”, loss of facial pain sensation, hoarseness
9?
what does this supply?
what are sx of stroke here?
Basilar artery
branches supply 1. the pons 2. anterior medulla
sx: paralysis and loss of sensation in the face, body and limbs; can also affect eye movements and cause diplopia

what does this supply?
what are sx of stroke here?
Anterior Inferior Cerebellar
supplies -
- inferior surface of cerebellar cortex
- dorsolateral pons
sx – ipsilateral cerebellar signs, facial paralysis, ipsilateral hearing loss, loss of pain and temp over face ispilaterally

what does this supply?
what are sx of stroke here?
superior cerebellar a.
supplies – 
- superior surface of cerebellum
- dorsolateral corner of rostral pons
sx – ipsilateral cerebellar signs, contralateral pain and temperature loss, Horner’s
supplies?
stroke sx?
posterior cerebral a.
supplies – occipital lobe, medial portions of parietal and temporal lobes, anterior & posterior midbrain, crus cerebri, posterior thalamus
stroke sx - if unilateral: blindness in the visual field contralateral to the affected side, alexia (left side).
if bilateral as with “top of the basilar” occlusion: bilateral blindness, memory loss, somatosensory loss, coma & death
