WebNerve = a bundle or bundles of nerve fibers. Ganglion = clusters of neuronal cell bodies in the peripheral nervous systems, as well as associated glial cells and axons. Therefore, ganglia can be distinguished from peripheral nerves by the presence of neuronal cell bodies. Axons are neuronal processes specialized for electrical impulse conduction. WebA ganglion is a group of neuron cell bodies in the periphery (a.k.a. the peripheral nervous system).

WebEach ganglion in the sympathetic chain innervates only one particular body segment. Fibers entering a sympathetic chain ganglion cannot pass through the sympathetic chain without synapsing within the sympathetic chain ganglion at the level of entry. Fibers entering a sympathetic chain ganglion must always ascend within the sympathetic chain. The preganglionic parasympathetic fibres originate in the inferior salivatory nucleus of the glossopharyngeal nerve. They leave the glossopharyngeal nerve by its tympanic branch and then pass via the tympanic plexus and the lesser petrosal nerve to the otic ganglion. Here, the fibers synapse and the postganglionic fibers pass by communicating branches to the auriculotemporal nerve, which conveys them to the parotid gland. They produce vasodilator and secretomotor eff…
