arterial supply of the brain Flashcards
ethmoid and frontal sinus supplied by
ophthalmic. a
what are the 2 branches which are close to the termination of internal carotid artery?
1- post. comminicating artery
2- choroidal artery
which of the following forming part of cirlce of willus ?
post.comminicating artery
cource of post.commincating.a ?
runs postriorly above “oculumotor.n”
choroidal artery gives branches to ?
crus cerebri , internal capsule , LGB, optic tract (because it runs close to the optic tract )
when ACA will join ACA in oppisite side ?
after entering the longtudinal fissure of cerebrum by ant.comminicating.a
ACA join ACA by
ACA
ACA join PCA by
PCA
“leg area” supplied by
ACA
cortical branches of ACA is :
1- “ leg area”
2- parieto-occipital sulcus
3- strip of cortex
central branches of ACA :
1- internal capsule
2- caudate neucleus
3- lentiform nuclei
MCA supply all lat.surfece of hemisphere except
1-narrow strip (ACA)
2- occopital pole+ inf.lat.surface of hemisphere(PCA)
MCA supply all motor area except
leg area
ant.perforating substance
MCA supply all motor area except
any artery to supply deep strucutre of the hemiscphere must pass inly through
ant.perforating substance
central branches of MCA :
same as ACA
which of the folloiwing supply the visual.cortex
PCA
cortical branches of PCA
1- hemisphere : inf.lat + med
2- occipital lobe : med + lat
central branches of PCA
1- mid brain 2-thalamus 3-MGB 4-pineal 5- lentiform neucleus
