[Morphology of the ciliary ganglion (author's transl)].
Microscopic examination of the ciliary ganglion shows the presence of large peripheral and moderately-sized central neurones. The appearance of the intraganglionic neurones suggests that they are of the parasympathetic type, sensory fibres and sympathetic fibre bundles passing through the ganglion without synapses. Afferent fibres are long and thin and have no collateral endings, while efferent fibres are short and thick. Afferent nerve fibres have either a very thin or no myelin sheath, whereas post-ganglionic fibres are richly myelinated.
