D

Posterior Spinal a. 

3

Anterior spinal a.

provides - ventral 2/3 of spinal cord

medial medulla

 

 

branch in spinal cord -

1. paralysis

2. loss of pain and temp below stroke

 

branch in medulla

1. contralateral sesnory loss and paresis

2. ipsilateral tongue paralysis

what does this supply? 

what are some sx? 

PICA

supplies:

1. cerebellum

2. cerbellar cortex

3. dorsolateral medulla and pons

sx: Wallenburg’s syndrome: vertigo, loss of balance, ipsilateral “cerebellar signs”, loss of facial pain sensation, hoarseness

5

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 -

1. inferior surface of cerebellar cortex

2. 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 -- 

1. superior surface of cerebellum

2. 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
