Here's a little chart, courtesy of a great Physiology student:
| Peripheral Nervous System | Central Nervous System |
| nerves | tracts |
| ganglia | nuclei |
| Schwann cells | oligodendrocytes |
Part of the Peripheral Nervous System (PNS) is the involuntary part, consisting of efferent neurons controling visceral organs. This is called the visceral nervous system, but more commonly known as:
Autonomic Nervous System
Autonomic = Automatic = Involuntary
Sympathetic & Parasympathetic divisions. Here's a silly little video that shows the functions of each.
Sympathetic Division
Location: Thoracic and Lumbar regions of spinal cord
3 Kinds of pathways
Parasympathetic Division
Location: Brain, and Sacral region of spinal cord
Receptors
This is super fun, talks about the brain, gets deep and slightly philosophical, and mentions reflexes. It's all about the brain! :)

My daughter's doctor told me that she is going to have to get some autonomic nervous system testing and I am a nervous wreck about it. I have been doing some research to get a better understanding. This was very helpful, thanks so much for sharing.
