Figure 1. This cross section is stained with
osmium. The black rings reveal the myelination. The cut
nerve axons are wrapped into bundles in a fashion similar to
skeletal muscle. Magnification is 400X.

Figure 2. This longitudinal view of an axon
reveals a Node of Ranvier. The gap is where the saltatory
action potential is boosted.

Figure 3. This cross section reveals part of
the spinal cord at low magnification. Posterior or dorsal
is to the top. Ventral or anterior is to the bottom.
Notice the difference between gray and white mater.

Figure 4. This is a high magnification view
(400X) of the ventral motor horn area. The white space
around the somas is an artifact of preparation.

Figure 5. Low power view (40X) of the ventral
horn area revealing the cell bodies of the motor
neurons.
