since the mature secretory granules in the small granule chromaffin ( sgc ) cell were argentaffin and were mainly located along the cell membrane , this cell was clearly distinguishable under the light microscope both from the a ( adrenaline ) cell whose secretory granules were non-argentaffin and from the na ( noradrenaline ) cell whose cytoplasm was rich and was filled with large , strongly argentaffin granules .
