I post this now because I believe it is relevant to my prior post, What is consciousness for? The sensory or afferent nerves are involved in all awareness. The motor or efferent nerves are involved in all volitional bodily movement -- of legs, arms, hands, fingers, head, jaws, etc. So the nervous system links awareness/consciousness and volitional movement. The article 'What is consciousness for?' also links consciousness and volitional movement, but makes only one brief mention of the nervous system.
