The autonomic nervous system is the involuntary portion of the motor division.

• A. True
• B. False
• C. It is part of the central nervous system
• D. It is the somatic nervous system

Answer: (B)

The key idea is how motor commands are organized into somatic and autonomic pathways. The autonomic nervous system controls involuntary actions of the body's internal organs—heart, lungs, digestive tract, glands—operating largely without conscious control. It has its own branches (sympathetic and parasympathetic) that adjust activity based on needs, stress, and rest. Because these functions run largely automatically, the autonomic system is the involuntary portion of the motor division. In contrast, the somatic nervous system handles voluntary control of skeletal muscles. While some people can influence autonomic responses a bit through techniques like controlled breathing or biofeedback, the default state of autonomic activity remains involuntary.
