Between neurons, there are two primary methods in which an impulse or action potential can reach another neuron, via a chemical and electrical synapse.
Chemical synapse
This involves a chemical messenger and the fact that both neurons are not physically connected, rather the chemical must diffuse across a synaptic cleft to pass on the message. Chemical synapses tend to be slower than electrical ones.
This type of synapse is often found in the muscles.
Electrical synapse (a.k.a. gap junctions)
This may also involve a chemical messenger however generally they are the charged ions directly from the action potential. Additionally, the connection between different neurons are physical and direct, resulting in a generally faster connection than a chemical synapse.
This type of synapse is often found in the heart.
Neurotransmitters are molecules that travel from the synapses of one neuron to the dendrites of another neuron, activating channels on the second neuron that allow an influx of ions to rush in and start an impulse within the second neuron.
The impulses can only travel from the axon of one neuron to the dendrite of another neuron.
The synaptic cleft prevents an impulse from being transmitted directly from one neuron to another.
A synapse--basically the junction of an axon of one neuron, a space (called the synaptic cleft) and the dendrites of another neuron.
a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.
Electoral impulse
one second
synapse is that junction through which impulse can be transmitted from one neuron to another.
Synapse
A nerve impulse passes from an axon terminal of one neuron to another neuron across a synaptic gap.
Neurotransmitters are molecules that travel from the synapses of one neuron to the dendrites of another neuron, activating channels on the second neuron that allow an influx of ions to rush in and start an impulse within the second neuron.
Acetylchoine in the synpases mediates transmission of impulse from one neuron to another.
Synapse
They function to convey an impulse from one neuron to another.

Messages travel from one neuron to another through the neurotransmitters. Each neuron has dendrites which receive messages from other neurons.
