Flashcards in Flaccid Dysarthria Exam 1-Dr. Blaesing's Questions Deck (124)
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?
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?
Patient presents with hypernasality. Which cranial nerve is implicated?
Xth Vagus-Pharyngeal branch
Which intrinsic laryngeal muscle is the primary pitch changer?
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?
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?
Are LMN’s part of the PNS?
Are LMN’s part of the Final Common Pathway?
Do LMN’s originate in the cortex?
Do UMN’s (including both DAP and IAP) terminate at the synapses either in the brain stem or spinal cord?
Which subsystems can dysarthria effect?
At which anatomic level (supratentorial, etc.) do cranial nerves III-XII originate?
Which cells form myelin in CNS?
All oligendroglia cells
Name the structures that make up the basal ganglia
a. Globus Paladus
Make up the Striata:
b. Caudate Nucleus
Define UMN and their function
Cell bodies originating in the motor cortex.
Job=tells LMN what to do
Define LMN and their function
Cell bodies originating in the brain stem and spinal cord. Destination=muscle sending message to.
Function=to take the message from UMN and execute it.
The patient presents with tongue atrophy & fasiculations. Upon tongue protrusion, the tongue deviates to the right. Your best estimation is that it is a: (UMN or LMN) lesion and the lesion is on which side (Left or Right)?
How is Dysarthria different than Apraxia?
Apraxia is motor programming and dysarthria is muscle weakness/muscle execution
