Summary
Three different ganglia each of the sympathetic and the parasympathetic nervous sytem of Syrian golden hamsters were comparatively investigated by means of electron microscopy.
-
1.
It appears that in the perikarya ergastoplasm and free ribosomes are distributed in islet-like formations more distinctly within the sympathetic neurons than in the parasympathetic neurons.
-
2.
Granules of the so called catecholamine-type exist in both sympathetic and parasympathetic neurons in comparable size and number, except for the ciliary ganglion in which they occur very rarely. They originate evidently in the Golgi apparatus. Similar granules occur also in the synapses of the sympathetic and the parasympathetic ganglia.
-
3.
Myelinated nerve fibers are more abundant in the parasympathetic than in the sympathetic ganglia of the golden hamster.
Thus, the comparative examination does not show essential ultrastructural differences between sympathetic and parasympathetic neurons in the species investigated.
Zusammenfassung
Je drei sympathische und parasympathische Ganglien des Goldhamsters wurden elektronenmikroskopisch vergleichend untersucht. Folgende Befunde wurden erhoben:
-
1.
Freie Ribosomen und Ergastoplasma erscheinen in den Perikaryen sympathischer Ganglienzellen deutlicher inselförmig geordnet als in denen parasympathischer Zellen.
-
2.
Granula vom Typus der Katecholaminkörnchen kommen in den parasympathischen Ganglienzellen und in den sympathischen Ganglienzellen in annähernd gleicher Form und Zahl vor; sie entstehen offenbar im Golgiapparat. Auch in den Synapsen der parasympathischen und sympathischen Ganglien treten Granula vom Typus der Katecholaminkörnchen auf. Das Ganglion ciliare zeichnet sich jedoch durch Armut an derartigen Granula aus.
-
3.
In den parasympathischen Ganglien des Goldhamsters kommen markhaltige Nervenfasern häufiger als in sympathischen Ganglien vor.
Die vergleichende Untersuchung läßt somit keine wesentlichen Unterschiede in der Ultrastruktur sympathischer und parasympathischer Neurone der untersuchten Species erkennen.
