- Cell Biology. the appendage of the neuron that transmits impulses away from the cell body.
Origin of axon
Examples from the Web for axone
From the base often near its middle arises one large fibre—the axone fibre, which conducts impulses away from the perikaryon.
In some few cells the axone breaks up into branches in the immediate neighbourhood of its own perikaryon in the cortex.
In most cases, however, the axone runs off into the subjacent white matter, leaving the cortex altogether.
In the dog, an animal with high olfactory sense, the axone of each olfactory neurone is connected with five or six mitral cells.

Word Origin and History for axone
"axis of the vertebrate body," 1842, from Greek axon "axis" (see axis).
- The usually long process of a nerve fiber that generally conducts impulses away from the body of the nerve cell.
- 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.
