Arterial Supply to the Brain Flashcards
Label this image of the blood supply to the brain.
The anterior circulation of the brain is fed by which vessels?
Internal carotid arteries
The posterior circulation of the brain is fed by which vessels?
Vertebral arteries
The major motor pathways are supplied by which vessels?
From which vessel do these vessels arise?
Lenticulostriate arteries
Arise from the middle cerebral artery
Which arteries are responsible for the blood supply to each part of the cerebellum:
- Superior
- Middle
- Inferior
Superior- superior cerebellar artery
Middle- anterior inferior cerebellar artery
Inferior- posterior inferior cerebellar artery
The majority of the lateral aspect of the cerebral hemispheres, lateral aspect of the sensory and motor homonculus and the superior aspect of the temporal lobe are supplied by which artery?
Middle cerebral artery
The medial portions of the frontal and parietal lobes are supplied by which vessel?
Anterior cerebral artery
Which vessel is responsible connecting the left and right anterior cerebral arteries to complete the circle of willis?
Anterior communicating artery
The left and right vertebral arteries converge together in the midline to form which vessel?
The basilar artery
The small arteries that branch from the basilar artery are known as what?
What structure do they supply?
Pontine arteries
Pons
What is the significane of the pontine arteries during neurosurgical procedures?
Can give the patient locked in syndrome if these vessels are damaged
Which arteries are responsible for connecting the the anterior and posterior circulation of the brain?
Posterior communicating artery
What is the purpose of the branching arrangement of the Cirle of Willis?
To allow some collateral supply incase of blockage
