So now that we've talked about the interaction with our sympathetic,
let's talk about the parasympathetic division.
In the parasympathetic division, we also have preganglionic neurons.
The cell bodies of these are going to be located in the nuclei of the four cranial nerves:
cranial nerve III, cranial nerve VII, cranial nerve IX, and cranial nerve X.
Also, these cell bodies are located in the brain stem
and finally, the cell bodies in the lateral gray matter of sacral segments 2 through 4 of the spinal cord.
There are two different outflows from the parasympathetic division.
The first outflow is the cranial parasympathetic outflow.
These are going to extend from the brain stem and four of the cranial nerves.
The second outflow is the sacral parasympathetic outflow.
This outflow extends from the 2nd through the 4th sacral spinal nerves.
The parasympathetic ganglia only has one type of ganglia.
Those are the terminal ganglia.
These lie near the visceral organs or sometimes are actually within the walls of the organs themselves.
