Aphasia Exam 1 Questions with Correct Answers Rated A+
Frontal Lobes - Answers voluntary control of movement throughout the body
aphasia is - Answers an acquired neurogenic language impairment that can result in loss of a previous
held ability to understand or produce speech and/or the ability to read or write
neuroplasticity is - Answers the adaptation of the brain's structure and functions throughout an
individuals lifespan in response to environmental pressure, experiences and challenges
factors that influence language recovery in aphasia - Answers spontaenous neural regeneration
site and extent of lesion
age and education
motivation
type and amount of language treatment
environment
the motor strip sends neural messages to muscles via - Answers pyramidal system
Extrapyramidal system - Answers voluntary control of motor behavior
supplementary motor cortex - Answers ability to initiate spontaneous utterances impaired by lesions in
this area
prefrontal cortex - Answers responsible for synthesizing sensory stimuli and coordinating them with
plans for action (contributes to abstract thinking, problem solving, and judgement EF)
-damage: behavior and personality changes, impaired judgement, poor strategic planning and impaired
insight
Temporal lobes - Answers hearing and analysis of auditory signals
-posteriorportion of the superior temporal gyrus (Wernicke's) is auditory association areas- analyzes
auditory stimuli to the point of comprhenesion
-medial temporal lobes- important for memory
Parietal lobes - Answers damage to this area can produce a loss of sensation of touch and an impaired
recognition of one's own body (asomatognosia) and a loss of the ability to appreciate spatial concepts
occiptal lobe - Answers vision
higher order analysis takes place in the visual association cortex (medial and lateral surfaces of occiptal
lobe)
, Limbic system - Answers memories, feeilngs, the desire to produce language and the emotional coloring
of thought
Zone of language - Answers -located within the distribution of the middle cerebral artery
-surrounds the sylvian fissure on the lateral surface of the hemisphere
Lesion for Broca's - Answers left lateral frontal, pre-Rolandic suprasylvian region, often extends
posteriorly to include the parietal lobe
-superior division of the middle cerebral artery
aphemia - Answers pure word dumbness, pure motor aphasia (loss of ability to articulate words)
-lesion limited to inferior pre-Rolandic motor strip (muscles controling glossopharyngeal apparatus)
Lesions for Wernicke's - Answers lesions in the posterior third of the superior temporal gyrus
-distribution of the inferior division of the middle cerebral artery
primarily temporal lesion produces - Answers word-deaf variant in which reading may be less affected
may have difficulty understanding individual spoken words but can understand in context
temporal lesion that extends posteriorly - Answers visual connections are disrupted, more difficulty
understanding written language and language in context but relatively less difficulty with isolated words
Lesions for conduction aphasia - Answers supramarginal gyrus and white matter pathways (arcuate
fasciculus)
-lesions in an alternative white matter bundle through the inferior parietal lobule
-combination lesion affecting the left primary auditory cortex, insula and underlying white matter
-left tph
Temporal lesions and conduction aphasia - Answers -afferent type of aphasia, in which repetition would
be impaired because of defective memory
parietal or insular lesions and conduction aphasia - Answers efferent type of aphsai- problems with
phonemic representation
different lesion sites for anomic - Answers -angular gyrus
-second temporal gyrus
-left inferior frontal area (action naming)
-left temporal region (noun naming)
