A posterior communicating – common area of aneurysm, oculomotor palsy
B anterior circle of willis – general sensory and motor dysfunction, and aphasia
àC middle cerebral artery – most common site of thrombosis
D anterior communicating artery – mc circle of willis aneurysm
E anterior cerebral artery – medial surface of brain, leg foot motor and sensory deficits


middle cerebral artery is most common site of thrombosis in stroke
Middle cerebralartery provides circulation to lateral aspect of brain including those regions involved in productionand comprehension of speech (broca’s and wernicke’s speech areas)

Aphasias

Wernicke’s - FLUENCY intact REPITITION OF SPOKEN LANGUAGE poor COMPREHENSION impaired SITE OF LESION posterior temporal lobe, superior temporal gyrus (brodmann 22)

Global - FLUENCY impaired REPITITION OF SPOKEN LANGUAGE poor COMPREHENSION impaired SITE OF LESION both broca and wernicke’s areas affected

Conduction - FLUENCY intact REPITITION OF SPOKEN LANGUAGE poor COMPREHENSION intact SITE OF LESION arcuate fasciculus, interconnects broca and Wernicke areas
