“…The most important argument for the proponents of the possibility of a morphological classification became the presence of several long processes in type II neurons and of one long and several short processes in other neurons. The validity of this distinction was sufficient for many authors (Hill 1927;Tiegs 1927;van Esveld 1928;Oshima 1929;Iwanow 1930;Harting 1931;Lawrentjew 1931; Kolossow and Sabussow 1932;Reiser 1932;Murat 1933;Cavazzana and Borsetto 1948;de Biscop 1949;Jabonero 1951Jabonero , 1958Jabonero , 1960Stöhr 1949Stöhr , 1952Greving 1951b;Temesrékási 1955;Kolossow and Milochin 1963) and resulted in "collapsing of the classifications" (Furness and Costa 1987), which furthermore frequently referred to only two types of neurons. The characteristic flat and lamellar shape of the type I dendrites -"lamellenförmig" (Dogiel 1899; "Dendritenlamellen"; Lawrentjew 1929) became a facultative feature for the differentiation of type I neurons.…”

“…The characteristic flat and lamellar shape of the type I dendrites -"lamellenförmig" (Dogiel 1899; "Dendritenlamellen"; Lawrentjew 1929) became a facultative feature for the differentiation of type I neurons. Based on the shapes and lengths of their short processes, occasional subdivisions of the type I neurons had been proposed, but these merely underlined the general grouping into two types of enteric neurons (Hill 1927;Lawrentjew 1931;Greving 1951a, b;Temesrékási 1955;Jabonero 1958Jabonero , 1960.…”

The first differentiation of enteric neurons into three morphological types was done by the russian histologist A. S. Dogiel on the basis of the different shapes and lengths of their dendrites. Although a number of authors considered his results during the following decades, only a division into two types withstood time: type I neurons had one long and several short processes, whereas type II neurons were characterized by several long processes. Some further structural features were discussed but substantial progress was not made until the late 1970s. This stagnation was due to some inaccuracies in Dogiel's descriptions, to the fact that most histologists in this field followed the reticular concept of the nervous system, to the idea that enteric neurons represent no more than a vegetative, postganglionic relay station between the central nervous system and the periphery, and to methodological difficulties. With the application of modern neuroanatomical techniques it was realized that the enteric nervous system contains a considerable number of neuronal subpopulations. The search for morphological correlates of the chemical diversity of enteric neurons was done mainly in the pig and the guinea-pig. In the pig, additional structural features such as axonal projection, distribution of neurons within ganglia, within different plexuses and along the length of the gut, blood supply etc. were included as criteria for further refining neuronal classification. Most of our knowledge about functional features of enteric neurons, e.g. chemical coding, neuronal connectivity, electrophysiological behaviour, was derived from studies in the guinea-pig small intestine. In light of interspecies differences, comparison of findings from different species is mandatory. The search for morphological and functional peculiarities of human enteric neuronal circuitry has to consider all methodological and conceptual advances made within the past 100 years since the pioneering work of Dogiel.

Two types of surgery were performed on domestic cats to establish the source and functional significance of the apparatuses we have denominated perivascular, perifascicular and free endings of the oesophageal submucous layer. After extirpation of the cranial regions of the sympathetic ganglionic chain, of all the cervical ganglia and of the four proximal thoracic ganglia, no Wallerian degeneration of the concerned nerve endings was observed, thus ruling out their dependence on this neural pathway. After ablation of the central portion of the nodose ganglion, of the vagal nerve. Wallerian degeneration was observed in these nerve-ending apparatuses, thus demonstrating: (i) that these nerve apparatuses depend on perikarya situated in the nodose ganglion and (ii) that they are sensory receptors.

The osmium tetroxide-zinc iodide technique has been applied to the study of the tela submucosa and tunica muscularis in the esophagus of the cat and the rhesus monkey. Other than the classical terminal vegetative formation, three types of endings were found, classified as perifascicular, free and intramuscular. The comparative results between cat and rhesus monkey show differences in the distribution and number of such endings. A sensory functional significance is proposed and discussed.
