cerebral ventricle
fourth ventricle
function of ventricles
Anterior circulation: derived from internal carotid artery via aortic arch
posterior circulation: derived from basilar artery via subclavian artery
circle of willis
Middle cerebral artery
MCA upper and lower branches provide blood supply to lateral hemisphere surfaces
affects Broca’s area, primary auditory cortex, most of primary motor and somatosensory cortex, Wernicke’s area, angular and supramarginal gyri, and arcuate fasciculus
MCA includes branches that supply blood to the frontal, parietal, and temporal lobes
infarct at junction between ICA and MCA interrupts blood flow to all perisylvian speech and language areas
deeper infarcts (further into cerebral hemispheres) may produce more localized deficits
