title: [Electrophysiologic and histochemical characteristics of the fiber composition of the subdiaphragmatic portion of the vagus nerves].
abstract: The fibre composition of subphrenic branches of the vagus nerves was studied electrophysiologically and histochemically. In anaesthetized cats, the presence of multicomponent electrical responses was found during stimulation of preganglionic fibres of splanchnic nerves in the splanchnic branch of the dorsal vagus trunk; the presence of synaptically interrupted fibres was shown. Histochemically, adrenergic fibres were found both in the central and in the peripheral stumps of subphrenic branches of the vagus nerves. Most strongly fluorescent fibres were regularly found in the peripheral stump of the splanchnic branch of the dorsal vagus trunk. The data obtained suggest that processes of ganglionic neurons of the celiac plexus ascend within splanchnic and other branches of the vagus nerves.
