Exam 1 Part 4 Flashcards
What does spastic dysarthria sound like?
Talking through tight muscles, can be intelligible, very strained
What are the top 3 etiologies of spastic dysarthria?
Stroke, TBI, degenerative disease
Made up of the lower motor neuron system and PNS
Final common pathway
What is the function of the final common pathway?
Stimulates muscle contraction and movement
What are 4 types of things that happen if there is damage to the final common pathway?
Paresis, paralysis, atrophy, fasiculations
Condition that happens if some motor neurons are okay after damage to the final common pathway
Paresis (weakness)
Condition that happens if all input from LMN is gone
Paralysis
Wasting, loss of muscle tissue
Atrophy
Twitches of muscle caused by excess or spontaneous motor unit activity
Fasciculation
What are the 3 areas of lesions in the FCP for flaccid dysarthria?
LMN, muscles, neuromuscular junction
61% of flaccid dysarthria are due to what 2 things?
Surgical trauma, neuropathology’s of undetermined origin
What surgery is a common cause of flaccid dysarthria?
Carotid endarterectomy
What disease is common in damage to the neuromuscular junction?
Myasthenia gravis
What cranial nerves are important for speech and language?
V, VII, IX, X, XI, XII
What cranial nerves, if damaged, can cause flaccid dysarthria (5)?
V, VII, IX, X, XII
