Explanation:

These blanks refer to key subdivisions of the nervous system in biology. The first is the branch of the peripheral nervous system that regulates internal organs. The next two are the opposing subdivisions of that system: one activates the body's fight-or-flight response, while the other regulates rest and energy conservation.

Answer:

1. Autonomic Nervous System

• The part of the peripheral NS
• Controls the glands and the muscles of the internal organs (i.e. heart)

1. Sympathetic Nervous System

• Division of the autonomic NS
• Arouses the body, mobilizing its energy in stressful/threatening situations

1. Parasympathetic Nervous System

• Division of the autonomic NS
• Calms the body, conserving its energy
