draw the circle of willis xxx
Label A-C
A: anterior cerebral artery
B: middle cererbral artery
C: internal carotid artery
under normal circumstances, what are the anterior and posterior communicating arteries like?
closed !!
classic circle of willis is seen in ~1/3rd pop
label A-D [4]
A: vertebral artery
B: superior cerebellar artery
C: posterior cerebral artery
D: basilar artery
when does collateral circulation open? [1]
collateral circulation should only open when there is a pressure difference (increased pressure can open anterior / posterior communicating arteries)
what is most normal variant in cerebral arterial circle? [1]
what is most normal variant in cerebral arterial circle? [1]
one / both posterior communicating arteries are missing (e & f)
what are the main branches of the internal carotid artery? [4]
- opthalmic artery: orbit & retina. connects to external carotid artery
- posterior communicating: connext with carotid & vertebral artery system
- middle cerebral artery: connects to basal ganglia and lateral 2/3rds of cortex
- anterior cerebral artery: connects with medial side frontal & parietal lobes, anastamoses with MCA
