Hemisphere responsible for expressive and receptive language
Left hemisphere
Know what they want to say but cannot find the right words to use, usually intact receptive language
Broca’s aphasia
Unable to comprehend speech, with their own speech being often devoid of meaning
Wernicke’s aphasia
Where is the Broca’s area located?
Inferior-posterior region of frontal lobe
Where is the Wernicke’s area located?
Posteriorly located along the superior marginal gyrus of temporal lobe
Runs down the middle lateral surface of each cerebral hemisphere; divides the frontal lobes and parietal lobes
Central sulci
Begins at lower front of each two cerebral hemispheres at an upwards angle passing the central sulci; Divides temporal lobes from the frontal and parietal lobes
Lateral sucli
What are the frontal lobe functions?
Expressive language, personality, some memory, motor movement
____ primary motor cortex issues motor plans for speech
Left
Damage near base of motor strip often creates _____ of speech
Apraxia
