Answer 5

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 are sx of stroke here?

Answer 8

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
