Cerebrovascular System (Carotid Artery System (Divides into Internal and…

- - - - Anterior Cerebral Artery (ACA)
        
        Supplies blood to frontal and parietal lobes
        
        Clinical correlates: paralysis in legs, feet, toes; prefrontal lobe symptoms; impaired executive functioning
      - Middle Cerebral Artery (MCA)
        
        Supplies blood to lateral surface of brain
        
        Clinical correlates: tactile agnosia, aphasia, reading and writing deficits
- - - - Gives rise to Anterior Inferior Cerebellar, Pontine, and Superior Cerebellar Arteries
        
        Anterior Inferior Cerebellar supplies blood to inner ear; damage results in ipsilateral deafness
      - Posterior Cerebral Artery (PCA)
        
        Branches from basilar artery
        
        Connects to MCA via Posterior Communicating Artery (Circle of Willis)
        
        Supplies blood to occipital lobe
        
        Clinical correlates: homonymous hemianopsia, blindness, visual agnosia, memory impairments
    - - Occlusion of Anterior Spinal causes ipsilateral paralysis of tongue and face
