C. the corticocerebellar control circuit and its connections to the extrapyramidal system
D. the extrapyramidal system, upper motor neurons, and lower motor neurons

12. Regarding phonation of individuals with ataxic dysarthria, which of the following statements
is FALSE?
A. Voice tremors are very common phonatory deficits in ataxic dysarthria.
B. Few patients with ataxic dysarthria present with phonatory deficits.
