Motor system pathway
Nettet6.4 Disorders of the Cerebellum. Like the basal ganglia, the cerebellum has historically been considered part of the motor system because damage to it produces motor disturbances. Unlike the basal ganglia, damage to the cerebellum does not result in lack of movement or poverty of movement. Instead, cerebellar dysfunction is characterized by … Nettet28. jun. 2024 · The corticobulbar system controls brainstem nuclei that innervate cranial muscles. Parallel and Serial Processing. Although the motor system is organized hierarchically, the hierarchy is not a simple chain of processing from higher to lower areas. Many pathways enable the different levels of the hierarchy to influence each other.
