Which statement describes the function of the Central Nervous System and Peripheral Nervous System?

• The Peripheral Nervous System functions to process input from the Central Nervous System, and if necessary, triggers a response to act on the input.

• The Central Nervous System is responsible for connecting and triggering the muscle cells throughout the body to respond to stimuli.
