The different ion concentrations on the inside and outside of the cell membrane create a certain electric potential around the cell (just by being there with their charge).
A strong enough change in the concentrations can cause certain ion channel proteins in the membrane to open all at once, allowing certain ions to massively diffuse through the membrane and thereby rapidly changing the potential.
When a certain potential is reached, these channels will begin to close again and different potential-controlled channels will open, allowing a different kind of ions to move through the membrane and returning the membrane potential back to the previous state.
Again through diffusion the now changed ion concentrations will trigger these so-called action potentials in nearby membrane regions, carrying the stimulation along the neuron's axon to the next neuron.
Neurons pass information by neurotransmitters, chemicals that activate receiving neurons. These molecules (neurotransmitters) pass through what is called the synapse: a junction of an axon of the first neuron close to the dendrite of a second neuron. When the neurotransmitters act on the receiving neuron, they can activate a series of changes that cause than neuron to signal to another neuron, resulting in a chain reaction.
After the message gets to the axon terminal, it needs to cross the synapse. To cross it, the message converts to neurotransmitters. Then they cross the gap between the 2 neurons which is called the synapse. On the dendrites there are receptors , and the neurotransmitters go with their designated receptor.
the dendrites get the information and send it down the axon to the axon terminals
Generally, no. The postsynaptic areas on the dendrites of a neuron are where many signals enter the neuron.
axon
The part of the neuron that picks up information and sends it to the cell body is the dendrite. Electrical stimulation is transmitted by upstream neurons onto dendrites, and the dendrites integrate and determine the extent to which action potentials are produced.

The end of one neuron, the presynaptic button, sends messages to other cells by releasing neurotransmitters (chemical messengers) into the synaptic cleft (a small space between two neurons). The other cell, whether it be a neuron, a muscle, a sweat gland, etc., will receive this message at the post synaptic membrane of its cell, and will respond accordingly.
The axon terminals of one neuron links with dendrites of the neighboring neuron.

Dendrite to soma to axon ;)

the axon
The axon carries information from one neuron to another while the dendrites of a neuron receive information from other neurons
The question isn't clear enough. Does it mean the part that sends info. through the neuron (the axon)? Or does it mean the part that sends information to other neurons (the synapse)?
An axon terminal is the structure of a neuron (a single cell of the central or peripheral nervous system) at the end of it's axon that forms a synapse with another neuron. Generally, the axon terminal is the point at which a neuron passes information to the neurons with which it is connected.

The axon is the part of the neuron that can carry information for long distances.
