What are the 2 main parts of the Central Nervous System?
The spinal cord and the brain
What are the 2 next categories of the Peripheral Nervous System?

What are the 2 parts of the Autonomic Nervous System?
The Sympathetic Nervous System and hte Parasympathetic Nervous System
What does the Central Nervous System do?
It is the body’s control system
What does the Peripheral Nervous System do?

It does this for both voluntary and involuntary movements
What does the Sympathetic Nervous System do?
Mobilizes body responses to threat by increasing heart rate and respiration and drawing stored energy reserves
What does the Parasympathetic Nervous System do?
Replenishes bodily resources by promoting digestion and slowing down other bodiy processes
