Extrapyramidal Motor Pathways

The extrapyramidal motor pathways are concerned with automatic (nonvolitional) control of body parts. This particularly includes patterned, sequential movements or actions. Thus, the major command system of the human nervous system uses these pathways. There are several extrapyramidal motor pathways. Having multisynaptic circuits throughout the CNS, they use many intermediate relays before reaching the effector organs. The cerebellum of the brain plays a major role in extrapyramidal pathways; the cerebellum is the major center for coordinating the patterned sequential actions of the body, such as walking.
