    What is the difference in site of lesion for spastic and flaccid dysarthria?

    • Spastic is bilateral damage to the upper motor neuron. Flaccid is unilateral damage to the upper motor neurons.

    • Spastic is bilateral damage to the upper motor neuron. Flaccid is damage to the lower motor neurons.

    • Spastic is unilateral damage to the upper motor neuron. Flaccid is bilateral damage to the lower motor neurons.

    Correct Answer
    A. Spastic is bilateral damage to the upper motor neuron. Flaccid is damage to the lower motor neurons.
    Explanation
    Spastic dysarthria is characterized by bilateral damage to the upper motor neurons, while flaccid dysarthria is caused by damage to the lower motor neurons. Upper motor neuron damage affects the pathways that control voluntary movements, resulting in increased muscle tone and spasticity. Lower motor neuron damage affects the nerves that directly innervate the muscles, leading to weakness, flaccidity, and reduced muscle tone. Therefore, the correct answer is that spastic dysarthria is caused by bilateral damage to the upper motor neuron, while flaccid dysarthria is caused by damage to the lower motor neurons.

    What type of damage causes flaccid dysarthria?

    • Bilateral upper motor neuron

    • Final common pathway (LMN)

    • Unilateral upper motor neuron

    Correct Answer
    A. Final common pathway (LMN)
    Explanation
    Flaccid dysarthria is caused by damage to the final common pathway (lower motor neuron). The final common pathway consists of the cranial nerves that directly innervate the muscles involved in speech production. Damage to this pathway can result in weakness, atrophy, and reduced muscle tone, leading to difficulties in articulation, phonation, and overall speech production. Bilateral upper motor neuron damage would typically cause spastic dysarthria, characterized by increased muscle tone and spasticity. Unilateral upper motor neuron damage would not typically result in flaccid dysarthria.

    What is the difference between fasciculations and fibrillations?

    • Fibrillations are arrhythmic, isolated twitches or dimplings seen at rest. Fasiculations cannot be seen and are detected via EMG

    • Fasciculations are arrhythmic, isolated twitches or dimplings seen at rest. Fibrillations are observed

    • Fasciculations are arrhythmic, isolated twitches or dimplings seen at rest. Fibrillations cannot be seen and are detected via EMG

    Correct Answer
    A. Fasciculations are arrhythmic, isolated twitches or dimplings seen at rest. Fibrillations cannot be seen and are detected via EMG
    Explanation
    Fasciculations are involuntary muscle contractions that can be seen or felt on the surface of the skin. They are arrhythmic and occur at rest. On the other hand, fibrillations are also arrhythmic but cannot be seen with the naked eye. They are detected using electromyography (EMG), a diagnostic test that measures the electrical activity of muscles. Therefore, the correct answer states that fasciculations can be seen at rest while fibrillations cannot be seen and require EMG for detection.
