The occlusion of which artery causes ipsilateral hypoglossal palsy with contralateral pyramidal signs

ANT spinal artery

Medial medullary syndrome--ASA

[ArchivalUser]

I will add this ..yes this is Medial Medullary Syndrome due to occlusion of the ANTERIOR SPINAL ARTERY -ASA )
Symptoms :
1.IPSI hemiparesis of the tongue ( nucleus /gfibers of nerve XII )
2.CONTRA decrease dsicriminative touch ( medial lemniscus )
3.CONTRA upper motor neuron sign 9pyramids )
4.PAIN& TEMPRETURE ARE SPARED !!!!!!!!!!!!!!!!!!!!!!!!

AND WHY THEY SPARED ?
tHIS IS WHAT i KNOW AND CORECT ME IF i AM WRONG, ok ?
mOST OF THE SPINAL CORD IS SUPPLIED BY A PAIR OF POSTERIOR ARTERIES AND ANTERIOR SPINAL ARTERY.
tHE ANTERIOR SPINAL ARTERY ( FROM THE VERTEBRAL ARTERIES ) SUPPLY THE anterior 2/3/ OF THE SPINAL CORD WHRES THE POSTREIOR SPINAL ARTERY MOSTELLY SUPPLY THE DORSAL COLUMNS AND DORSAL HORN OF THE SPINAL CORD.

tH EPOSTERIOR ARTERY ALSO SEND COLLATERALS DOWN AROUND THE LATERAL AND NVENTROLATERAL FRINGES OF THE CORD.tHIS IS THE BASIS OF PHENOMEN ACALLED "SACRAL SPARING " IN WHICH pain &tempreture SENSATION IN THE spinithalamic tract FROM THE sacrum AND legs IS REPRESENTED MOST LATERALLY AN DIT IS THEREFOR SPARED BY THE BLOCAGE OF THE ANTERIOR SPINAL ARTERY !!!!!!!!!!!!!!!

occlusion of anterior spinal artery or vertebral artery can produce contralateral pyramidal signs and ipsilateral XII nerve signs.

what the answer?
