Quizplus · Accepted Answer

The somatic nervous system is responsible for the voluntary movements of skeletal muscles, such as those involved in writing. The axon causing the muscle contraction is part of this branch of the nervous system. The central nervous system includes the brain and spinal cord, while the sympathetic and parasympathetic nervous systems are part of the autonomic nervous system, which controls involuntary actions such as breathing and heart rate.
