Abstract

Eränkö and Härkönen (1963), when studying formaldehyde-induced fluorescence in the superior cervical ganglion, noted the extremely bright fluorescence of a few single, small cells. They called these cells “small intensely fluorescent cells” or, more commonly, used the acronym “SIF cells” (Eränkö and Härkönen 1965a, b). At the fine-structural level SIF cells are characterized by abundant electron-dense granules, the subcellular catecholamine-storing organelles, and therefore have been termed “small granule-containing cells” (SGC cells, Matthews 1971; Matthews and Raisman 1969). Obviously these cells are paraganglionic cells and some authors prefer to classify them accordingly (Heym 1978a). The appearance of paraganglionic cells in the sympathetic ganglia depends on the techniques used for their visualization. The above-mentioned terms (SIF cells, SGC cells) will be used as synonyms in this section to describe the various manifestations of paraganglionic cells.
