In the dog, an animal with high olfactory sense, the axone of each olfactory neurone is connected with five or six mitral cells.
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.
axon ax·on (āk'sŏn') or ax·one (-sōn')
The usually long process of a nerve fiber that generally conducts impulses away from the body of the nerve cell.
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.
