During embryonic development the mesoderm is divided into the segmented somite (making, among other things, the striated muscles that power locomotion) and the unsegmented lateral plate (making, among other things, the smooth muscles of the gut). The dual nervous system follows this embryological division: the somatic (voluntary nervous system) innervates the striated muscles, and the visceral (involuntary nervous system) innervates the smooth muscles.
