Once the action potential reaches the end of the axon it needs to be transferred to another neuron or tissue. Then the postsynaptic cell responds according to the neurotransmitter. Includes action potential, excitatory & inhibitory neurotransmitters and neurotransmission.

To summarise the process of synaptic transmission in chemical transmission, the presynaptic neurone receives information via its dendrites, which contain many synapses, from other nerves. An action potential arrives at the axon terminal. Release of neurotransmitters into the synapse.

Membrane depolarization from action potential causes influx of calcium ions.
This allows electrical signals to flow directly between cells, making transmission nearly instantaneous. First, an action potential propagates down the axon until it arrives at the axon terminal, depolarizing the membrane of the presynaptic terminal.

There are a series of steps that take place during chemical synaptic transmission. This communication occurs at junctions called synapses. Docking of synaptic vesicles at the membrane. Synaptic transmission can be broken down into steps.
Information is passed down the axon of the neuron as an electrical impulse known as action potential.
Neurotransmission starts with the release of a readily available neurotransmitter from the presynaptic neurone, followed by its diffusion and binding to the postsynaptic receptors. Synaptic transmission is the process by which one neuron communicates with another. At its core, synaptic transmission is the way in which nerve cells, or neurons, communicate with each other.
