“…SIF cells in the rat SCG have been studied extensively and, in this species, some or all of them receive preganglionic innervation and at least some of them synapse with principal ganglion cells (Matthews and Raisman, 1969;Williams, 1967;Williams and Palay, 1969;Yokota, 1973). Most rat SIF cells occur in clusters and are in close relation to fenestrated capillaries (Siegrist et al, 1968) (Fig.…”

“…Efferent synapses on the GC cells in the rat superior cervical ganglion have been reported by many authors (Williams 1967;Siegrist et al 1968;Williams and Palay 1969;Matthews and Raisman 1969). Yokota (1973) revealed with serial ultrathin sections a GC cell which forms both afferent and efferent synapses. Matthews and Nash (1970) showed soma-to-soma efferent synapses between GC and ganglion cells.…”

In the rat superior cervical ganglion, small granules, 100-150 nm in diameter, and large granules, 80-280 nm in diameter, were seen in the granule-containing (GC) cells. Most GC cells contained almost exclusively the small granules (SG type cell), while a few cells almost exclusively the large granules (LG type cell). The GC cells formed both efferent and cholinergic afferent synapses.The efferent synapses were about four times as many as the afferent ones. In the major pelvic ganglion of rats, SG type and LG type cells were present in comparable numbers.Cells with both types of granules were also noticed. Ovoid-shaped granules, 60 X 140 nm with a core of moderate electron density, were observed in some SG type cells. Both afferent and efferent synapses were noted on GC cells in this ganglion.The latter were more numerous than the former. SG type cells formed more synapses than LG type cells. Based on these observations, the physiological significance of GC cells was discussed. ----SIF cell; innervation; monoamine granule; rat superior cervical ganglion; rat major pelvic ganglionSince the discovery of granule-containing (GC) cells (small intensely fluorescent cells, SIF cells) in the autonomic ganglia (Eranko and Harkonen 1963;Hamberger et al. 1963), a number of studies have been performed to clarify the morphology and functional significance of these cells. Grillo (1966) and Siegrist et al. (1966) noted afferent, or incoming, synapses on GC cells in the superior cervical ganglion. Williams (1967) observed efferent, or outgoing, synapses on the GC cells and suggested these cells to function as interneurons. Heym and Williams (1979) insisted that the GC cells release monoamines into blood vessels in the shrew (Tupaia glis) superior cervical ganglion. On the contrary, Eranko and Eranko (1971) and Lever et al. (1976) proposed that the GC cells have a chemoreceptor function like chief cells of the carotid body. Siegrist et al. (1966Siegrist et al. ( , 1968 classified the GC cells in the superior cervical ganglion of the rat into two types based on the morphology of the granules. Watanabe (1971) revealed four types of GC cells in the guinea pig hypogastric ganglion. Lu et al. (1976) observed three types of GC cells in the rat superior cervical ganglion and celiac-mesenteric ganglion.

“…The I-type GC cells are located in the autonomic ganglia, being synaptically interposed between the pre-and postganglionic neurons in the rat superior cervical ganglion (WILLIAMS, 1967;MATTHEWS and NASH, 1970;MATTHEWS, 1971;YOKOTA, 1973) or between two postganglionic neurons in the turtle cardiac ganglia (YAMAUCHI et al, 1975a;YAMAUCHI, 1976). They are likely to act as an adrenergic modulator for gangllonlc transmission (LIBET and OWMAN, 1974;WILLIAMS et al, 1975b;YAMAUCHI, 1976).…”

“…It must be noted, however, that the vagal postganglionic neurons are thought to have an axon or collateral branches that form reciprocal synapses with GC cells as found in the turtle cardiac ganglia (YAMAUCHI et al, 1975a;YAMAUCHI, 1976). Although YOKOTA (1973) suggested the possible occurrence of a reciprocal synaptic junction between a GC cell and a sympathetic postgangli.onic neuron in the rat superior cervical ganglion, this remains to be proved.…”

“…There seems to be firm evidence by now that these cells act as an adrenergic modulator of the neuronal activity by means of their synapses with neurons or through their local and/or general endocrine functions (MATTHEWS and RAISMAN, 1969;BOOK, 1970;BECKER, 1972;ABBOTT and HOWE, 1972;YOKOTA, 1973;ELLISON and HIBBS, 1974;VERNA et al, 1975;MORGAN et al, 1975;FURNESS and SOBELS, 1976;HERVONEN et al, 1976;YAMAUCHI, 1976).…”
