AXON – A Long Fibre that CARRIES IMPULSES AWAY FROM THE CELL BODY. Each neuron has only ONE AXON. The Axon Ends in a series of small swellings called AXON TERMINALS.

All messaging along the neurons are driven at first by a stimulus. This can be chemical or electrical. This begins a change in the neuronal cell membrane called depolarization. One small section is depolarized and that causes the next small section to become depolarized. The first section is repolarized in nanoseconds so that the stimulation can be repeated. This "flipping of the charge" travels rapidly to the effector. This could be a muscle.
This entire process is called the action potential. The stimulus must be strong enough to begin the process.

The axon carries the signal away from the neuron, while the dendrite carries the signal to the neuron.
The cell body of a neuron (a nerve cell) receives signals from its neighbors; when prompted thereby to send a signal of it's own, the axon (an extension protruding from the body) propagates that signal electrochemically via an "ion pump" to other neurons at the terminal synapse (a small gap between one neuron and the next). At the synapse, chemicals are released into the surrounding fluid to stimulate the next neurons in the chain.
The connection between neurons is called a synapse, and the sending region is normally an extended "tail" called an axon. However, in some presynaptic connections, the same sending function is done in a dendrite or soma (the bulbous end of a neuron, containing the nucleus, is called the soma or perikaryon).
A good way to remember this is: "Axon and Away both start with A."
axon. they are nerve cell structure wich carries impulses away from cell body to dendrites
Commonly its the axon.
Dendrites have also been discovered to be able to do this, though.
