- (B) Raising your hand to answer a question is a voluntary motor movement controlled by the
somatic nervous system. The parasympathetic and sympathetic systems are the two parts of the
autonomic nervous system; they control involuntary functions such as heart rate and digestion. The
central nervous system includes the brain and spinal cord. Although they would have played a role
in telling Gonzo to raise his hand, taking that action was ultimately enabled by the motor neurons in
his somatic system.
