Fig. 1.3.05. Perikaryon of the unipolar nerve cell from the trigeminal ganglion. N - nucleus of ganglion cell. Inset shows ganglion cells in light microscopy of toluidine blue semithin (0.5 µm) sections from tissue embedded in epoxy-resin and prepared for electron microscopy. This approach offers high resolution views intermediate between conventional light microscopy and electron microscopy. Scale = 10 µm.
