[Luminescent-histochemical study of the sympathetic innervation of the large intestine in some mammals].
It has been established that specifically fluorescening fibres and their endings as well as neurons along the length of the large intestine and in the thick of its wall have uneven distribution in cats, albino rats and dogs. A considerable part of fibres are concentrated in the muscular-intestinal, submucose plexuses and in the circular muscular layer. The greatest amount of fibres can be found in the rectum wall. They form various synaptic contacts mainly with parasympathetic neurons. Such connections with the bundles of smooth muscles are not very numerous. An exclusion is the rectum because in its wall there are equally many endings of both kinds. Solitary fibres and their endings are referred to the neurons of intramural ganglia. Their amount here is not great, most frequently they are found in cranial portions of the large intestine.
