An axon (from Greek ἄξων axōn, áxōn), axis is a, long slender projection of a nerve, cell or, neuron that typically conducts electrical impulses away from the'neuron s cell. Body myelinated axons are known as nerve. fibersn certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the electrical impulse travels along an axon from the periphery to the cell body, and from the cell body to the spinal cord along another branch of the same axon.
