This cross-sectional image was stained with H&E and is at a sufficiently high magnification to identify very specific structures within the ganglion. The ganglion will contain a number of nerve fibres and cell bodies of the neurons. There are approximately 30 discrete nerve cell bodies visible in this image although there are no clear nerve fibres visible.

In some of the cell bodies it is possible to distinguish a faint ring which represents the centrally located axon. The cell bodies themselves are spherical and have retained a pale staining and in some there is an intensely stained nucleus. Surrounding these cell bodies are ''Satellite cells'' that appear to be continuous with the Schwann cells surrounding the nerve. These satellite cells often appear to be clustered and are much smaller than the cell bodies.
