Slide 3 Higher power of multipolar neuron in gray matter stained with silver. Processes may be dendrites of local neurons, or axons of distant neurons either passing through the field or ending upon local neurons. A large, multipolar, motor neuron of the anterior horn, seen whole, with all its processes stretched out in a spinal cord smear. Notice the dark clumps of Nissl substance in the cytoplasm. The axon cannot be identified with certainty in this particular view.
Neuroglial nuclei surround the neuron.
Slide 5 Glial nuclei seen in white matter of the cord, cut so that nerve processes are seen running longitudinally. Slide 6 Silvered preparation of astrocytes, showing their many fine cytoplasmic processes. Note their close relationship to capillaries, the heavy black structures. Since astrocytes touch both capillaries and neurons, they are thought to play an important intermediary role in the nutrition and metabolism of neurons.
