Sympathetic Ganglion. Sympathetic ganglia contain the cell bodies (perikarya) of postganglionic sympathetic neurons and represent the site where they synapse with the. preganglionic sympathetic neurons. In contrast to the sensory ganglia, these cells bodies are randomly scattered about the ganglion. Their nuclei tend to be eccentrically located within the cell. Usually large groups of nerve fibers are not present as in the sensory ganglia.

The image on the right is a higher magnification of that on the left showing several cells bodies (black arrows) of postganglionic sympathetic neurons. Note the eccentric nuclei.
