The Histogenesis of the Spinal Ganglia
Author: Ennio PannesePublisher: Springer Science & Business Media
ISBN: 3662103389
Category : Medical
Languages : en
Pages : 97
Book Description
The present review is based on the data of the literature, and on the personal experience gained by the author in recent years by studying the histogenesis of spinal ganglia. Probably, the reader will find more than one gap in the biblio graphy. The author would like to point out that in no case are such gaps due to the voluntary omission of any information, interpretations, or views. The gaps are due only to the difficulties met in trying to master such a vast literature consisting of so many contributions which have appeared over more than a century. An endeavour has been made to report not only the morphological data, but also, whenever possible, information derived from histochemical and biochemical studies. 11. Origin 01 the Spinal Ganglia Before 1868 it was generally thought (see, e.g., Remak, 1851; Bidder and Küpffer, 1857) that the spinal ganglia arise from the mesoblast of the protoverte brae (old term for somites). In 1868 His showed that the nerve cells of the spinal ganglia take their origin from the ectoderm, and more precisely from a thin band of ectoderm (Zwischenstrang, neural crest) flanking each side of the neural plate (Fig. 1 a) and interposed between it and the somatic ectoderm (Hornblatt). On this subject His (1879) wrote in a later paper " ... die spinalen Ganglien ... aus einem schmalen Substanz streifen hervorgehen, welche zwischen der Medullarplatte und dem Hornblatte gelegen ist und dessen Material ich als Zwischenstrang bezeichnet habe."

Book Description
The visual system of insects has attracted histologists for a long time. We have detailed histological studies of the visual systems of Diptera, Hymenoptera and Odonata dating from the last century: Leydig's (1864) study on optical ganglia of insects, Ciaccio's (1876) on the fine structure of the first ganglion in the mosquitos and Hickson's (1885) giving for the first time an exact description of the three optical ganglia of Musca. From 1896 several papers appeared using neuro histological methods, mainly Golgi techniques and methylene blue staining. In 1896 Kenyon published his work on the bee-brain and in 1897 described the relationships of neurons in the optic ganglia with a modified Golgi method. Another work, by Jonescu (1909), should be mentioned: "Vergleichende Unter suchungen am Gehirn der Honigbiene". In the same year Cajal's findings on the optic ganglia of the fly were published; then in 1915 Cajal and Sanchez wrote a definitive monograph on the neural elements and their connections in the same animal that remained the main reference in this field for decades. In both works Golgi techniques were used. Since then there have been only a few new publications on the subject: (Gribakin, 1967; Perrelet and Baumann, 1969 a, b; Perrelet, 1970; Varela and Porter, 1969; Skrzipek and Skrzipek, 1971, 1973; Grundler, 1972: Snyder, Menzel and Laughlin, 1973). They deal mainly with the receptors of the retina.
The Development of the Visual System of the Albino Rat

Book Description
Most authors who have studied the whole visual system described the fiber connections between the different nuclear centers (Monakow, 1883, 1889; Probst, 1900; Minkowski, 1913, 1920, 1934; Kosaka and Hiraiwa, 1914; Put nam, 1926; Oshinomi, 1930; Papez and Freeman, 1930; Lashley, 1931, 1934a, 1934b, 1941; Barris and Ingram, 1933/34; Le Gros Clark and Penman, 1934; Waller, 1934; Chang, 1936; Gillilan, 1940; Le Gros Clark, 1942; Krieg, 1946a, 1946b, 1947; Nauta and Bucher, 1954; Hayhow et al., 1962; Lund, 1966; Mon tero, 1968). The histogenetic and cytogenetic differentiation of the various components of the visual system has been treated in numerous individual studies mostly on the cerebral cortex and the retina and to a lesser degree on the superior col liculus and the lateral geniculate body, however, it has not yet been investigated under the aspects of developmental interactions of a functional system on the basis of comparing the development of the different brain parts involved with re spect to the establishment of a functionally interrelated system. The first concepts of the histological differentiation of the neural tube and parts of the more advanced central nervous system were based on the classical neuroblast-spon gioblast-theory of His (1889, 1904), Cajal (1911, 1960) and Lorente de No (1922, 1933, 1949). The development of the definitive cerebral cortex with its 6 laminae according to Tilney (1933) was attributed to three successive cell migrations which form the supragranular, granular and infragranular layers.
Heavy Metals in the Brain

Book Description
The importance of transition metals and group II b metals in biological reac tions is becoming increasingly clear. Such metals form an integral part of the structure of many enzymes and non-enzymic proteins and also feature in more reversible interactions between metal ions and large or small biological molecules (Johnson and Seven, 1961). As discussed at the end of this paper, chemical analyses have shown the presence of these metals in the central nervous system and some hypotheses have been advanced concerning their role in more specific nervous activities such as synaptic processes. In order to define more precisely the role of these trace metals it is clearly necessary to investigate their regional and cytological distribution, as may be achieved by the use of histochemical methods. Some of the earliest neurohistochemical studies were concerned with trace metals, especially iron, in the brain (Spatz, 1922). Later reports on the localiza tion of trace metals have been comparatively few, except as regards the hippo campal region. Maske's report (1955) that intravital injections of the coloured chelating agent, dithizone, revealed an accumulation of zinc within the hippocampus, prompted aseries of investigations by Fleischhauer and Horstmann (1957), Timm (1958a), McLardy (1960, 1962, 1963, 1964), von Euler (1962), and others, in which the intravital dithizone method or Timm's sulphide silver method was used. As a result, particularly intense staining was found to correspond to the zones receiving mossy fibre terminals (Cajal, 1911; Blackstad et al., 1970).

Book Description
The presence of nerve cells in the white matter of the spinal cord and in the spinal and cranial nerves has attracted the attention of some researchers in the past. Because of their location in such unexpected regions, these neurons provided a rich field of speculation regarding their nature and function. This was partic ularly true about the nerve cells lying in the spinal white matter. From phylogenetic considerations, neurons in the spinal white matter are present more abundantly in amphibians, reptiles and brids than in mammals. A. brief survey of literature on lower vertebrates indicates that GASKELL (1885, 1889) was the first to describe the displaced neurons in the white matter of the spinal cord of alligators and various species of birds. In his consideration they were displaced ganglion cells. In 1902 von KOELLIKER gave an exhaustive account of such neurons in the white matter of the spinal cord of reptiles and birds. In these animals he observed clusters of such neurons running in longitudinal columns and thus was able to group them into nuclei known as "Hofmann's nuclei". Further, he suggested that these nuclei arise from the mass of the ventral horn and that they may give rise t. o preganglionic fibers, motor fibers or ventral commissural fibers. In t. he ensuing years investigation of these nuclei was extended by STREE TER, KRAUSE, TERNI, HUBER and others (quoted from ARIENS KAPPERS et. aI. , 1960, Vol. I, p. 206-210).
