Fig. 3a: Cross section through human spinal cord (lumbar region, L1) showing motor neurons. H&E method used. Astrocytes and oligodendrocytes are labeled 'A' and 'O', respectively. The objective magnification used is 40x.

Fig. 4: Cross section through human spinal cord showing motor neurons located in ventral horn. Reduced silver method used. Silver grains are labeled 'S'. The objective magnification used is 40x. 

Fig. 5a: Cross section through human spinal cord showing close-up view of internal structure of motor neuron located in the body of dorsal horn. Reduced silver method used. Silver grains are labeled 'S'. An oil immersion lens 100x has been used.
