speech


neuromuscular features that underlie dysarthria - correct answer ✔strength,
timing, tone, speed (rate), range, direction (accuracy)


how are perceptual properties the 'gold standard' in the evaluation of MS
disorders? - correct answer ✔how sounds are perceived to sound is
important in distinguishing what is happening


requirements of a fine motor skill - correct answer ✔a. Accuracy and speed
b. Motor flexibility
c. Improves w/ practice
d. Automatic control


theory of motor equivalence related to speech - correct answer ✔It tells us
that there is more than one to achieve a perceived sound/output- it is not a 1:1
relationship between vocal tract shapes and target outputs

,CNS includes: - correct answer ✔brain and spinal cord


PNS includes: - correct answer ✔all neural tissue outside the CNS


3 functions of the brain stem - correct answer ✔1. conduit

2. superior laryngeal- Innervates cricothyroid muscle- adjusts length of vocal
folds (changes pitch)
3. recurrent laryngeal- Innervates intrinsic muscles of the larynx (except
cricothyroid)


symptoms with a lesion high in the vagus nerve- - correct answer
✔Hyponasality, resonance changes


symptoms with a lesion low in the vagus nerve- - correct answer ✔changes
in vocal quality, reduced production and intensity


two cranial nerves are in close proximity to each other and may overlap
somewhat in function - correct answer ✔vagus and glossopharyngeal


3 important functions of the cerebellum - correct answer ✔Coordination of
voluntary movements
equilibrium (balance)
scaling the size of muscular action


lobes of the cerebellum - correct answer ✔Anterior (tucking in front),
posterior (largest, visible), Flocculonodular (tucked, smallest)


Why is the thalamus important? - correct answer ✔It is a collection of nuclei,
