Define PNS

Peripheral Nervous System? = contains only nerves and connects the brain and spinal cord (CNS) to the rest of the body. The axons and dendrites are surrounded by a white myelin sheath.

or
Parasympathetic Nervous System= a subdivision of the autonomic nervous system. It is reverses the effects of the sympathetic nervous system. This system is relaxing the body functions and reversing the "flight or fight" response caused by the Sympathetic Nervous System. It is the relaxtion mechanism

I searched Google under the key words "Peripheral Nervous System" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps a little more. Thanks for asking.

Thank's i'll remember that!!
