title: [Functional characteristics of the conduction pathways of the caudal sympathetic mesenteric ganglion in the monkey (Macaca rhesus)].
abstract: Chronic experiments in anesthetized monkeys showed that pathways from the preganglionic branches of the ganglion (the lumbar splanchnic nerves) to the postganglionic branches were represented by fibers with different conduction velocity which ran through the ganglion without interruption. These pathways are, probably, the afferents or fibers of postganglionic sympathetic neurons. In addition, synaptically contacting pathways are present. All peripheral nerves of the ganglion are connected with each other through synaptically contacting pathways. The preganglionic branches (the lumbar splanchnic nerves, intermesenteric tract) are the independent channels without tracts connecting them. The proper reflexes related to the function of the pelvic organs are assumed to be actualized by the fibers of the reflex are closed in the ganglion. The scheme of conducting pathways of the ganglion in monkeys is presented.
