| Question | Answer |
| Speech production is a _______ task. | Speech production is a motor task. |
| 5 levels of the nervous system involved in speech production are: Cerebral cortex subcortical nuclei brainstem spinal cord and ___________ | cerebellum |
| 3 separate motor subsystems of speech production are | pyramidal extrapyramidal cerebellar |
| Pyramidal system | controls voluntary movement of muscles, contains 3 tracts |
| 3 tracts of the pyramidal system | cortico spinal cortico bulbar cortic pontine |
| Corticospinal system controls | skilled movements in limbs |
| Corticobulbar | cranial nerves directly innervate muscles of speech |
| Corticopontine | goes to the pons, cerebellum, then cortex via thalmus |
| All three pyramidal system tracts contain | upper motor neurons from the cortex |
| EXTRApyramidal system connects | subcortical motor nuclei, basal ganglia |
| Motor disturbances of the extrapyramidal system are involuntary movement disorders or | dyskinesias |
| Akinesia | is no movement |
| bradykinesia is | slow movement |
