Axon (noun)

1. A long, slender projection of a nerve cell that transmits electrical and chemical signals to other nerve cells or to muscles.
2. The part of a nerve cell that carries signals away from the cell body.

Origin:

From the greek word 'axon' meaning 'axis'.

Examples:

1. The axon is an essential component of the neural network, transmitting signals from one nerve cell to another.
2. Injury to the axon can result in disruption of the neural signal transmission and cause neurological symptoms.
3. The axons of nerve cells can be up to several feet long in the human body.
4. The diameter of an axon can vary greatly, and the thickness of the axon affects the speed of the neural signal.
5. The axon and its protective covering, the myelin sheath, play a crucial role in the proper functioning of the nervous system.
