It is the traveling of the electrical signal down the length of a neuron.
The electrical impulse travels into the dendrites, the "input" of the neuron, and into the soma or "body" where the signal gets processed. From there, the processed signal travels down the axon or "output" and into the dendrites of another neuron.
Various muscles of lower limb and back and hip.Each nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip. a nerve impulse travels along the neuron in the form of electrical and chemical signals.
In the body, an electrical impulse travels through the neurons, or nerve cells, to send signals to and from the brain. The Dendrites of the neuron accept the impulse, send it through the soma, down the axon, and to the axon terminal, where it'll be sent to the next neuron, almost instantly.

there's the axon (the nerve) the electrical impulse goes down that and covering the axon is the myelin sheath, otherwise known as a fatty sheath which insulates and helps make the electrical impulse go faster. In between each myelin sheath there are synapses (gaps between each one) and the impulse has to cross the gap so neurotransmitters are released which bind to receptors on the other side creating another electrical impulse which makes it travel even faster.
The nerve that travels down a neuron axon is basically Action Potential.It is an electrochemical change that passes through the cell.
When an impulse travels to the brain, it is first received by sensory receptors, then sent through the neurons by an electrical current. When the neuron receives the signal from a sensory receptor or from another neuron, the nucleus processes the impulse and then sends it down the axon. When a neuron is resting, the inside of the cell has a negative charge caused by active transport of NA and K molecules. This is called the resting potential. When the impulse hits the axon, the electricity causes NA pumps to open, allowing a flow of positively charged the molecule into the cell, causing the charges to switch. This is called the action potential. As the impulse passes, the K pumps open, restoring the original charge. When the impulse reached the end of the axon, neurotransmitters chemically pass the impulse to the next neuron. ;

When an electrical signal, or impulse, reaches the end of an axon it triggers chemicals called transmitters. The electrical signals then become chemical ones as the transmitters cross the synapse, the gap between an axon and a dendrite. When they reach the dendrite of another neuron they spark a new electrical signal that then travels the length of that nerve cell. And it does this over and over until it reaches its destination.
Neurons carry messages by converting a chemical signal into an electrical one, and vice versa. The dendrites of the neuron receive "messages" from chemicals that were released by another neuron. These chemicals are called "neurotransmitters". The neurotransmitter stimulates the neuron to depolarize. This means that the neuron's cell membrane becomes more permeable to sodium, and sodium moves into the cell. This causes the electrical charge of the cell to change, because sodium is positively charged. When it moves into the cell, the inside of the cell (or neuron) becomes less negatively charged and more neutral. At the same time, the area outside the cell becomes more negatively charged because of the positive sodium ions leaving that space. This rapid change in electrical charge is called "depolarization" and is essentially an electrical impulse. If the electrical charge is drastic enough (i.e., it meets the "threshold potential" by changing by at least 15 to 20 millivolts) the electrical signal carries all the way down the neuron into the axon. In the axon, a myelin sheath, or fatty covering, covers the neuron and essentially acts as insulation so that the electrical impulse can travel more quickly. Once the impulse reaches the axon terminal, it signals neurotransmitters to be released from that neuron and be interpreted by another neuron. Hence, the process starts all over again. I apologize for this answer being so long, there really is no way to answer this question briefly.
