Flashcards in Language Deck (19):
1

speech

1. phonation
-vocal cords-10
-dysphonia-hoarse, whispering, breathy

2. articulation
-lips, tongue, palate, pharynx-7,9,10,12
-connections with cerebellar and extrapyramidal systems provide the motor cord needed
-slurred, choppy, indistinct

respiratory function

2

Language

communicating by means of symbols
-cerebral cortex in dominant hemisphere

3

What artery supplies the language centers?

MCA

4

Aphasia

disorder of previously acquired language ability due to a lesion in a cortical language center

5

fluency

ease, facility and quantity of speech regardless of content or meaning

6

comprehension

can follow verbal or written commands

7

repetition the phrase needs to be repeated perfectly true or false

true

8

WHen does imperfect repetition occur?

when there is a lesion in either perisylvian language center (broca's or wernicke's) or the connecting arcuate fasciculus

9

paraphasia

abnormal word or syllable substitution
-seen particularly in wernicke's aphasia

10

neologism

nonsensical or foreign sounding word or phase

11

Broca's aphasia

posterior inferior frontal lobe lesion in the dominant hemisphere

-fluency is very impaired
-comprehension is relatively preserved
-repetition is imperfect

-often an accompanying right hemiparesis since the lesion may also involve the primary motor cortex

12

Wernicke's aphasia

posterior superior temporal lobe lesion

-fluency is preserved
-comprehension is impaired
-repetition is imperfect
(may think patient is drugged)

13

Conduction aphasia

lesion of arcuate fasciculus
-pathway connecting broca's and wernicke's

-fluent
-imperfect rep
-comprehension intermediate

14

Global aphasia

extensive lesion that virtually damages the entire perisylvian language region

-severe hemiplegia
-nonfluent
-imperfect rep
-poor comprehension

15

Alexia

posterior parts of dominant hemisphere
impairment of reading when visual cortex is disconnected rom language centers critical for reading

16

Agraphia

posterior parts of dominant hemisphere
-lesion disconnects the motor cortex for the dominant hand from language centers critical for writing

17

Prosody

-semantic and emotional meaning of language as conveyed by changes in pitch, inflection tone or melody
-can convey mood

18

Lesion in non dominant posterior superior temporal lobe-opposite to wernicke's produces what type of aprosody?

receptive
-doesnt understand
-can't mimick
-can do

19

Lesion in non dominant posterior inferior frontal lobe opposite to broca's produces what type of aprosody?

expressive
-can't do
-can't mimick
-can understand
