Pseudounipolar neurons showing satellite cells and lipofucsin granules.

Multipolar Neuron in autonomic ganglion showing Satellite Cells

Node of Ranvier in H&E stained section of Sciatic Nerve. Neurokeratin is the protein left over after all lipids have been removed by the dehydration process during tissue preparation.

Node of Ranvier (Arrow) in teased nerve fixed with Osmium.

Axons cut in transverse section stained with H&E. Axons stain purple and myelin sheath shows as clear area around axon

Ventral motor neuron in spinal cord stained with basic dye. Nissl substance stains blue/purple because it is basophilic. What kind of cells are represented by the small round nuclei seen around the neuron?

Multipolar from smear of grey matter from the CNS. Note that all the processes except one contain Nissl substance and are dendrites. The process that has no Nissl substance is the axon. The axon is not always the largest of the neuron's processes.
