Chapter 4: Flaccid Dysarthria
QUESTIONS
Multiple Choice
1. Flaccid dysarthria is:

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

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
B. lateral motor neurons

D. lower 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

production?

9. The spinal nerve that is one of the most important nerves of respiration is the:
A. accessory nerve
B. vagus nerve
C. phrenic nerve
D. facial nerve
10. Which of the following is NOT a cause of flaccid dysarthria?
A. physical trauma
B. brainstem stroke

B. hyponasality, imprecise consonants, and breathy voice quality
C. hypernasality, overly precise consonants, and breathy voice quality
D. hypernasality, imprecise consonants, and harsh vocal quality
12. Of the following statements about treatment for flaccid dysarthria, which one is NOT true?
A. Treatment may involve surgery.
B. Treatment may involve compensatory strategies
C. Treatment is effective only when tasks involve strengthening muscles in nonspeech tasks.

B. hyponasality and monoloudness
C. hyponasality and varying volume
D. hypernasality and phonatory incompetence
15. Surgical treatments options for damage to the vagus nerve are:
A. a palatal lift and Teflon injection
B. a pharyngeal flap and Botox
C. Botox and Teflon injection
D. a pharyngeal flap and Teflon injection
Completion
16. The ___________ branch travels a “double back” route from the brainstem to the larynx.
It branches from the vagus nerve after leaving the cranium and then courses down near the heart
before turning upward, traveling up along the trachea, finally reaching the larynx.
17. The cranial motor neurons from the accessory nerve help innervate the intrinsic muscles
of the velum, pharynx, and ___________.
18. The spinal nerves play an important role in speech production because they provide
motor innervations for the muscles of ___________.
19. ___________ is a disease that affects the neuromuscular junction, with the primary
symptom being rapid fatigue of muscular contractions over a short time, with recovery occurring
after rest.
20. A prosthetic treatment that is essentially a dental retainer with a rear extension to help push
upward on the velum is called a ___________.
