Speech And Language Flashcards
What connects wernicke’s area to Broca’s area?
The arcuate fasciculus
Where does the primary language pathway begin?
Wernicke’s area (posterior temporal lobe)
Language comprehension
What is Broca’s area responsible for?
Production of meaningful language
What is the primary language pathway?
Wernicke’s area –> arcuate fasciculus –> Broca’s area –> motor cortex –> muscle movements (speech)
Where is the articulation of specific words merged with emotional context?
The non-dominant hemisphere
What is an area not of the general language pathway connected to Broca’s and wernicke’s area?
The inferior parietal lobe
What is aphasia?
Disturbances in comprehension or formulation of speech (fluent or non-fluent)
What is aprosody?
difficulty in producing or understanding the emotional content of speech
What is apraxia of speech?
Inability to translate speech plans into motor activity
What is dysarthrias?
Disturbances in muscular control that affect speech production
What is receptive aphasia?
Wernicke’s or fluent
Severe defects in auditory and verbal comprehension, can speak but it does make sense. They don’t realize they aren’t using the correct words
What is conduction aphasia?
Form of fluent aphasia
Damage to arcuate fasciculus or Gershwind’s territory
Good comprehension
Cannot repeat words - arcuate fasciculus
Cannot come up with specific words - Gershwind’s territory
May be frustrating - only short phrases
What is expressive aphasia?
Broca’s or non-fluent
Variable comprehension
Impaired verbal and graphic expression, including inability to organize or control context
Extremely frustrating
What is global aphasia?
A form of non-fluent where damage is to large cortical areas
No distinct pattern
Profound defect in both expression and comprehension
What is aprosody usually caused by?
Dysfunction in areas of the non-dominant hemispheres that structurally mimic wernicke’s and Broca’s area
