What does the somatic nervous system do? - ANSWER-motor and sensory
pathways that regulate voluntary motor control of the skeletal muscles
What does the autonomic nervous system do? - ANSWER-motor and sensory
pathways that regulate the bodies internal environment through involuntary control or
organ systems
