[Conduction pathways of the solar plexus in dogs].
The conduction pathways of dog's solar plexus were studied, using the recording of action potentials of the plexus nerves. Greater splanchnic nerves consists of two groups of afferent A-fibres (conduction velocity of 12-15 and 25-56 m/s), afferent C-fibres (conduction velocity of 0.4-2.0 m/s) and preganglionic B- and C-fibres (conduction velocity of 1.0-12.0 m/s). Afferent A- and and C-fibres pass through the solar plexus ganglia to the dorsal roots; preganglionic fibres terminate synaptically on ganglionic neurons, their axons pass in the peripheral nerves to the viscera. Pathways between the peripheral nerves were found; probably they form peripheral reflex arcs.
