Motor execution

direct pathway, basal ganglia, cerebellum

How does bilateral innervation affect speech structure damage?

all speech structures are bilaterally innervated, so when one side is damaged, the other side compensates (unilateral UMN dysarthria isnt very severe)

LMN issue, execution, weakness

bilateral UMN, execution, spasticity

cerebellum, control, incoordination

BG, control, rigidity, decreased ROM

BG, control, involuntary movement
