Fig. 1.3.03. Perikaryon of multipolar motor nerve cell from anterior horn of spinal cord. N - nucleus, n - nucleolus. Inset shows motor cell 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 = 3 µm. (Rat, spinal cord).
