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.
It's the Axon

They carry impulses to the cell body. Axons carry impulses away from the cell body.
Remember: Axons away, so dendrites carry messages from the cell, and axons carry them away.
No, axons carry impulses away from the nerve cell body.
dendrites
An axon will carry nerve impulses away from the cell body.
this is not true about neurons: dendrites carry information away from the cell body
It is specialised by being a long thin cell that is insulated to carry electrical messages around the body. x When you hurt yourself e.g. burn yourself your immediate reaction is to get away from the heat, this is because we can sence pain due to our nerve cells which then carry an electrical message to your brain which then says to get away from the source of pain.
axon
The dendrites carry impulses to the neuron's cell body. The axon carries impulses away from the cell body.
Messages from the neuron always travel from the cell body down the axon.
the function of the neuron's axon is to carry messages to other cells
The areas that have had the action potential are refractory to a new action potential.
