[Conduction pathways of the lumbar ganglia of the paravertebral sympathetic trunk in the rabbit].
The conducting pathways of the lumbar (L3-L5) sympathetic ganglia were studied in rabbits by recording action potentials evoked in the nerves of the ganglia by stimuli applied to their other nerves and intracellular recording. It is established that some presynaptic fibres enter the sympathetic chain via grey rami and then pass upward and downward making synaptic contacts with ganglionic neurons. Other fibres enter the sympathetic chain through white communicating rami and pass in descending direction giving collaterals to the neurons of the ganglia. Descending preganglionic fibres with different conduction velocity converge on ganglionic neurons.
