By a release & subsequent diffusion of chemicals called neurotransmitters across a very small gap between neurons, called a synapse.
How neurotransmitters are released:As an impulse reaches an end of a neuron, called an axon terminal, the impulse opens ion pores in that axon terminal which allows Calcium ions to enter, which cause the movement of small membrane bounded packets of neurotransmitter chemicals, called vesicles (like tiny water balloons), to move to the cell membrane, where the vesicles fuse into the cell membrane, thus releasing the contents, the neurotransmitters, into the small space (the synaptic cleft) between the axon terminal and the dendrite of the post-synaptic neuron (the neuron the impulse is traveling to). What neurotransmitters do when they reach the post-synaptic neuron:The post-synaptic neuron has many structures each of which are like a combination of a "well", and an open and close able tunnel. The "well" (or hole with a bottom) is a RECEPTOR for the neurotransmitter chemical, in that the neurotransmitter FITS into that well like a key into a lock. And when a neurotransmitter comes to (by diffusion) and enters that well, it affects the shape of the companion tunnel (ION PORE), such that the ion pore OPENS, thus allowing Sodium ions to enter the post-synaptic neuron (normally at a dendrite, the manifold tiny input structures for a neuron). original answer:Nerve impulse travelingThe impulse is actually an electrical current which 'flows' along the nerves cells their 'branches' dendrites and the junctions between nerves but it is not so simple as a regular electrical wire, because a complex biochemical process is also involved. This process is responsible to the first creation of the electrical current, to its recreation some additional times along its passing (- otherwise it would have died out because of the unbelievable lengths such an impulse travels), and to its recreation in any 'new' nerve cell it reaches.

A nerve impulse travels down a neuron through the process of depolarization and repolarization. When a stimulus is received, it causes a change in the electrical charge of the neuron cell membrane, leading to the opening of ion channels that allow ions to flow in and out of the cell. This generates an action potential that travels along the length of the neuron until it reaches the synaptic terminals, where neurotransmitters are released to communicate with the next neuron.
A temporal summation (multiple impulses close together in time) or a spatial summation (multiple impulses close together in space) can cause enough ion channels to open allowing enough positive ions to enter the cell to make the the cell sufficiently depolarized to trigger an action potential
It travels down the axon or tail lookin thing to the dendrites wich turns the electrical charges into chemical charges which enters the dendrites of the next cell down the Axon and so on.

The neurotransmitters of a neutron enable a nerve impulse to do what?
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
What is the route followed by nerve impulses when one neuron communicates with another?
When one neuron communicates with another, the nerve impulse travels down the axon of the presynaptic neuron, reaches the axon terminal, triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron's dendrites, initiating a new nerve impulse in the postsynaptic neuron.
What is the space through which a nerve impulse passes from one nerve cell to another called?
The space through which a nerve impulse passes from one nerve cell to another is called a synapse. It is a small gap between neurons where neurotransmitters are released to transmit signals between the cells.
A nerve impulse travels from one cell to another by passing from?
A nerve impulse travels from one cell to another by passing from the axon of one neuron to the dendrite of another neuron at a synapse. Neurotransmitters are released into the synaptic cleft, where they bind to receptors on the postsynaptic neuron, initiating a new electrical signal in the receiving cell.
Where do nerve impulses travel?
Nerve impulses travel through neurons, which are specialized cells in the nervous system. These impulses travel along the length of the neuron, from the cell body down the axon, to the axon terminals where they can then pass on the signal to another neuron or target cell.
What begins when a neuron is stimulate by another neuron in its environment?
A nerve impulse

Where does the nerve impulse travel from the reflex arc?
The nerve impulse typically travels from the sensory neuron to the spinal cord, where it is processed by interneurons, and then to the motor neuron to elicit a response from the effector organ or muscle.
What carries a nerve impulse from one neuron to annother?
Neurotransmitter.
What is the function of the dentrites?
Dendrites are attaches to the axon terminals of other neurons. The nerve impulse travel from other neurons into the corresponding neuron via dendrites.
What is a neuron that transmits a nerve impulse toward the central nervous system is called what?
A sensory neuron transmits a nerve impulse towards the central nervous system. These nerve cells activated by input, transmits sensory information.
Where does a nerve impulse start?
A nerve impulse typically starts at the dendrites of a neuron, where it receives signals from other neurons or sensory receptors. These signals are then transmitted down the axon of the neuron to the axon terminals, where they can communicate with other neurons or target cells.
Where is the neuron in the body?
Neuron is the nerve cells that carry messages to the brain .The various parts of neuron are dendrite ,axon ,nucleus , cell body and nerve ending . All the information from the environment is detected by the specialised tips of nerve cells .These receptors are usually located in our sense organs such as,nose , tongue and so on. The information acquired at the end of the dendritic tip of a nerve cell sets off a chemical reaction that creates an electrical impulse . This impulse travels from the dendrite to the cell body , and then along the axon ,to its end .At the end of the axon , the electrical impulse sets of the release of some chemicals . These chemicals cross the gap or synapse, and start a similar electrical impulse in a dendrite of the next neuron . This is how nerve impulse travel in a body
