Aphasia
Which structure is described as the doorway through which subcortical systems of the nervous system communicate to the cerebral cortex?
Thalamus
Co-occuring speech and language disorders might be difficult to clearly dx in UUMN dysarthria because
verbal output may be limited
visually evident dyskinesias are a salient non-speech sign in hyperkinetic dysarthria
True
It isn’t possible to see pts with UUMN dysarthria to show breathy or hypernasality.
False
Hypernasality seen in flaccid dysarthria is often due to damage in…
CN X
Hyperkinetic means…
Too MUCH movement.
Most common speech charactersitics of flaccid dysarthria include

True
Primary neuromuscular feature in pts with flaccid dysarthria is…

weak/affected
In UUMN dysarthria the speech characteristics are often described as mild or moderate.
True.
Final motor pathway refers to…
LMNs
Spastic dysarthria is caused by.

What structure is important for the initial planning of voluntary movements?
Association cortex
One of the nonspeech signs in hypokinetic dysarthria is action tremor.
FALSE
Tremor at rest
Mixed dysarthria is a result of…

Spastic
The most common articulation disorder associated with spastic dysarthria is…
Imprecise consonants
The dyskinesias that affect speech production are classified as “fast” or “slow”
TRUE
The pyramidal system is responsible for facilitating discrete, skilled motor movements, such as speech production.
TRUE
What non-speech signs are associated with UUMN dysarthria?
Unilateral lower facial weakness
Movement deficits in timing, force, range or direction is known as…
cerebellar ataxia
Damage to the direct activation pathway result in increased muscle tone, spasticity and over responses of reflexes
FALSE

Chorea
The most prominent signs/symptoms of ataxia are…
Articulation inaccuracy and scanning like prosody
What parkinsonism symptoms have the greatest effects on speech?
muscle rigidity, reduced ROM and slowed movement
Which dysarthria can be characterized by abnormally fast speech rate?
Hypokinetic
Damage to the indirect action pathway is a cause of strained vocal quality in pts with spastic dysartria.
TRUE
List the steps of the motor pathway to say the word “cat”
Association cortex > BG > Thalamus > Primary Motor Cortex > Pyramidal Pathway > LMN > Articulators
