This image shows a
ganglion called Meissner's plexus in the submucosa of the ileum. This ganglion
contains nerve cells of the parasympathetic branch of the autonomic nervous
system and the pre- and postganglionic nerve fibers associated with these
neurons. The neurons are characterized by their large size and their very
large nuclei (Nu), which often have prominent nucleoli. There are also supporting
cells, including satellite cells derived from Schwann cells, which form a
partial covering of the neuronal perikaryon.
