middle cerebral artery

46
Q

cortex above the lateral fissure; supplies lateral frontal cortex including precentral and postcentral gyri

A

superior division off of the middle cerebral a.

47
Q

cortex below the lateral fissure; supplies lateral temporal lobe, parts of the parietal lobe

A

inferior division off of middle cerebral a.

48
