Term
What are the two arterial systems that supply the brain?
Definition

vertebral-basilar (20%)

internal carotid (80%)

Term

Definition

posterior inferior cerebellar

anterior inferior cerebellar

superior cerebellar

Term
trace the arteries from the vertebral arteries to the anterior cerebral arteries.
Definition
vertebral arteries --> basilar arteries --> posterior cerebral arteries --> posterior communicating arterties --> (internal carotid --> middle cerebral arteries) --> anterior cerebral arteries (connected by anterior communicating arteries)
Term

precentral artery

central artery

postcentral artery

parietal artery

angular artery

 

Term

internal capsule

Term
What brain parts do the posterior cerebral arteries supply?
Definition

parts of:

anterior and posterior thalamus
