Well, within the CNS itself, such as in the brain, spinal cord, etc, the impulses are carried by GRAY nerve tissue, which is unmyelinated.
Outside of the CNS (e.g. in the body, arms, legs, etc), the impulses are primarily carried by WHITE nerve tissue, which is myelinated in order to provide insulation and facilitate greater conduction speeds.

The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell. The word "neuroglia" means "nerve glue." These cells are nonconductive and provide a support system for the neurons. They are a special type of "connective tissue" for the nervous system.
