Flaccid Dysarthria Exam 1-Dr. Blaesing's Questions Flashcards
A patient presents with a “flutter: in the check area. What cranial nerve is implicated?
VIIth Facial Nerve
In assessing AMR’s, which sound/syllable will mostly likely be affected with VIIth nerve damage?
“puh”
With bilateral VIIth nerve lesions patients may have difficulty saying bilabials, what is the likely substitution?
Lingual alveolar sounds (using their tongue)
Which nerve innervates the stylopharyngeus muscles?
IXth Glossopharyngeal Nerve
What does the stylopharyngeus muscle do?
Raises pharynx in speech & swallowing
Patient complains of pain going down back of throat. Which cranial nerve is implicated?
IXth-Glossopharyngeal
Patient presents with hypernasality. Which cranial nerve is implicated?
Xth Vagus-Pharyngeal branch
Which intrinsic laryngeal muscle is the primary pitch changer?
Cricothyroid
Which nerve innervates the cricothyroid muscle?
Xth Vagus-Superior Laryngeal
Which will have a more significant effect – lesion on the recurrent laryngeal nerve or a lesion above the pharyngeal nerve?
Above the pharyngeal nerve
An axon that originates from a motor neuron on the part of the motor cortex that controls the jaw will descend through the corticobulbar tract to synapse with which cranial nerve?
Vth Trigeminal Nerve-Motor & Sensory Mandibular Branch
The patient presents with tongue atrophy & fasciculations. Upon tongue protrusion, the tongue deviates to the right. Your best estimation is that it is a _______ lesion and that the lesion is on which side?
LMN-lesion on the right
The patient presents with spasticity. Upon tongue protrusion, the tongue deviates to the right. Is the lesion UMN or LMN lesion? The lesion is on which side? Where is the side of weakness?
UMN-Left Side-Right side (where tongue deviates)
The jaw hangs open at rest with little strength to resist closing. Describe lesion.
Cranial Nerve V Trigeminal, Bilateral lesion. But can’t tell if UMN or LMN
The jaw deviates to the right side. With this information can you tell which is the side of weakness? Which is the side of lesion?
Yes, Right
You don’t really know where the lesion is.
There is a single UMN lesion on the right side that affects the Vth nerve. Will there be a significant effect on speech?
No, because UMN and this is a bilateral nerve. (if LMN, yes)
Are UMN’s part of the CNS?
Yes
Are LMN’s part of the PNS?
Yes
Are LMN’s part of the Final Common Pathway?
Yes
Do LMN’s originate in the cortex?
No
Do UMN’s (including both DAP and IAP) terminate at the synapses either in the brain stem or spinal cord?
Yes
Which subsystems can dysarthria effect?
All
At which anatomic level (supratentorial, etc.) do cranial nerves III-XII originate?
Posterior
Which cells form myelin in CNS?
All oligendroglia cells
