The process of sending electrochemical messages from one neuron to another is called synaptic transmission. Here are the steps:

1. Generation of an Action Potential: The process begins when an action potential (electrical signal) is generated in the neuron's cell body.

2. Propagation of the Action Potential: The action potential travels down the axon of the neuron towards the axon terminal.

3. Release of Neurotransmitters: When the action potential reaches the axon terminal, it triggers the release of neurotransmitters (chemical messengers) from vesicles into the synaptic cleft (the gap between neurons).

4. Binding of Neurotransmitters to Receptors: The neurotransmitters cross the synaptic cleft and bind to specific receptors on the dendrites of the next neuron.

5. Generation of a New Action Potential: The binding of neurotransmitters to receptors can either excite or inhibit the next neuron. If the signal is excitatory and strong enough, it will generate a new action potential in this neuron, and the process repeats.

6. Termination of the Signal: The signal is terminated by reuptake (neurotransmitters are taken back into the neuron that released them), enzymatic degradation (neurotransmitters are broken down by enzymes), or diffusion (neurotransmitters drift away).

This process allows neurons to communicate with each other, transmitting signals throughout the nervous system.
