axon

 [ak´son]
the process of a nerve cell along which impulses travel away from the cell body. It branches at its termination, forming synapses at other nerve cells or effector organs. Many axons are covered by a myelin sheath formed from the cell membrane of a glial cell. adj., adj ax´onal.

ax·on

(ak'son),
1. The single process of a nerve cell that under normal conditions conducts nervous impulses away from the cell body and its remaining processes (dendrites). It is a relatively even filamentous process varying in thickness from about 0.25 to more than 10 mcm. In contrast to dendrites, which rarely exceed 1.5 mm in length, axons can extend great distances from the parent cell body (some axons of the pyramidal tract are 40-50 cm long). Axons that are 0.5 mcm thick or more are generally enveloped by a segmented myelin sheath provided by oligodendroglia cells (in the brain and spinal cord) or Schwann cells (in peripheral nerves). Like dendrites and nerve cell bodies, axons contain many neurofibrils. With some exceptions, nerve cells synaptically transmit impulses to other nerve cells or to effector cells (muscle cells or gland cells) exclusively by way of the synaptic terminals of their axons.
2. In neurology and other clinical work, the term axon is also used as meaning dendrites (q.v.), which term is seldom used clinically.

axon

The long fibre-like process of a nerve cell which, bundled together with many thousands of other axons, forms the anatomical structure known as a nerve. The axon conducts nerve impulses away from the nerve body.

axon 

The threadlike process of a neuron which conducts nerve impulses from the cell body to the neuron's ending (bouton) where it is transmitted via a synapse to another neuron, muscle or gland. Syn. nerve fibre (when it is sheathed). See neuron; synapse.
