An axon (from Greek á¼Î¾ÏÎ½ Ã¡xÅn, axis), is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body. Axons are also known as nerve fibers. The function of the axon is to transmit information to different neurons, muscles and glands.
axon definition. 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.
