The extrapyramidal system represents part of the motor pathway system that has synapses within the brain stem which is in contrast to those of the pyramidal system. The extrapyramidal tract is distinguishable from the pyramidal system as tracts do not run within the pyramids of the [[Hindbrain_-_Anatomy_%26_Physiology#Medulla_Oblongata|medulla oblongata]] and instead run outside. This pathway contains various multisynaptic pathways that relay within several nuclei in the brain. These nuclei are dispersed from the telencephalon to the [[Hindbrain - Anatomy & Physiology#Medulla Oblongata|medulla oblongata]] and may be visible grossly. Other parts of the extrapyramidal tract take origin from the tectum and reticular formation. These synapses within the brain stem make it possible for the for motor neurone signals to be influenced as they enter the ventral horn of the spinal cord. The [[Hindbrain_-_Anatomy_%26_Physiology#Cerebellum_Structure_.26_Function|cerebellum]] utilises this influence to ensure that movements are smooth and coordinated.
