Well, on this diagram here,
it is a picture or an image of one of these
postsynaptic neurons in a paravertebral ganglia
or part of the sympathetic ganglia. And there,
you don't see a lot of satellite cells around
the cell bodies. And that is because as I explained
before, these neurons have a dendritic tree,
communicating with preganglionic neurons. And
because of that vast dendritic tree, the satellite
cells cannot pack around as much as they do in
a sensory or a dorsal root ganglion. Here
is an example of a parasympathetic autonomic
ganglion. Remember I said they are located
out near the viscera, so that the postganglionic
neuron travels a very short distance to the
target tissue. And they are very hard to see
sometimes. They are very tiny. This is a section
in the tongue and you see a neuron rather
a large structure surrounded by a few satellite
cells embedded in the connective tissue areas
of the tongue. Those postsynaptic neurons,
the cell bodies you see labelled there, again they
travel a short distance and innervate glands
in the tongue shown here. Serous secreting
glands that secrete materials that flush out
fluid away from our taste buds so that we
can continually taste different tastes. It
is all controlled by secretion of the serous
glands or controlled by the short postganglionic
neurons travelling from postganglionic areas
out in the periphery.
