Study Notes
Extrapyramidal System
- The extrapyramidal tracts terminate in the spinal cord, basal ganglia, and cerebellum.
- The brainstem nucleus involved in the origin of the extrapyramidal system is the basal pontine nucleus.
- The extrapyramidal system is controlled by the basal ganglia, along with cortical motor areas.
- The following is NOT part of the origin of the extrapyramidal system: dorsal column-medial lemniscal system.
