the long threadlike extension of a nerve cell that conducts nerve impulses from the cell body Compare dendrite
n.

axon
(āk’sŏn’)
The long portion of a neuron that conducts impulses away from the body of the cell. Also called nerve fiber.
The part of a nerve cell or neuron that transfers a nerve impulse from the nerve cell body to a synapse with another cell. (See action potential.) Depending on the location of the cell, the length of an axon can vary widely. In some cases (such as the axons that form the spinal cord), they may be several feet long.
