Entire lateral surface of the cortex, including major regions of the frontal lobe. MCA is the biggest branch of the internal carotid artery. It supplies blood to major areas involved with motor & sensory functions + language, speech & hearing functions (i.e., motor cortex in the precentral gyrus, Broca's area, the primary auditory cortex, Wernicke's area, the supramarginal gyrus, the angular gyrus, somatosensory cortex).
Damage may result in strokes, aphasia, reading & writing deficits, contralateral hemiplegia, impaired sense of pain, temp, touch & position.
