Motor System I: Movement and Motor Pathways

Abstract

There are three major areas that are responsible for producing the fine motor movements in the human: the cerebral cortex, basal ganglia, and cerebellum. The motor cortex in the cerebral hemispheres and regions in the frontal lobe anterior to the motor-sensory strip provide voluntary control to all of the skeletal muscles in the body. Our understanding of localization in the motor system is based on studies following lesions at various levels of the neuroaxis.
