Assumptions

The central nervous system is the brain and spinal cord; every nerve outside them is peripheral.

The peripheral system has a somatic part (the muscles you choose to move) and an autonomic part (the organs).
•
The autonomic part has two sides: the sympathetic readies the body for action, the parasympathetic calms it.
