QUESTIONS
Multiple Choice

A. a motor speech disorder caused by disruption of the flow of neural impulses along the
upper motor neurons
B. a motor speech disorder caused by a disruption of the flow of neural impulses along the
lower motor neurons
C. a motor speech disorder caused by a disruption of the flow of neural impulses along the
upper and lower motor neurons
D. a cognitive disorder caused by a disruption of the flow of neural impulses along the lower
motor neurons
2. Flaccid dysarthria affects the muscles of:
A. respiration only
B. respiration and articulation only
C. respiration, phonation, and articulation, but not prosody or resonance
D. respiration, phonation, articulation, prosody, and resonance
3. The final common pathway refers to:
A. upper motor neurons

4. What are the six pairs of cranial nerves of speech production?
A. trigeminal, facial, glossopharyngeal, vagus, accessory, and hypoglossal
B. trigeminal, facial, glossopharyngeal, vagus, abducens, and hypoglossal
C. trigeminal, facial, glossopharyngeal, vestibulocochlear, accessory, and hypoglossal
D. trigeminal, facial, glossopharyngeal, vagus, accessory, and hyperactive
5. With bilateral damage, what nerve can have serious effects on articulation, as the patient may
not be able to sufficiently raise the jaw to produce most consonant and vowel phonemes,
particularly those requiring bilabial, linguadental, and linguapalatal contact?
A. trigeminal
B. facial
C. glossopharyngeal
D. vagus
6. Which cranial nerve originates in the brainstem at the medulla and courses out to the
pharynx, where it innervates the stylopharyngeus and superior pharyngeal constrictor
muscles, which assist in elevating and opening the upper pharynx?
A. trigeminal
