S1: Blood Supply - Distribution Flashcards
blood supply to the (general) lateral portion of the cerebral hemispheres
MCA
what supplies the medial surface of the parietal and frontal lobes?
ACA
What structures does the MCA supply?
precentral g., postcentral g, (except leg and foot areas of M1 and S1) wernickes, brocas, primary auditory cortex, insula, frontal lobe
What does the ACA supply?
medial surface of the parietal and frontal lobes. including the leg and foot regions of M1 and S1
What does the PCA supply blood to?
medial parts of temporal and parietal lobes
occipital lobe
anterior and posterior midbrain
crus cerebri
posterior thalamus
* primary visual cortex, parts of temporal lobe involved in memory
What supplies blood to the anterior midbrain
PCA and Posterior communicating
